The last few presidential elections have prompted debates about age limits on politicians.

In today's political climate, it's hard to find thoughtful, respectful discussions online, especially when people disagree on an issue. We've all seen the way public discourse can break down into personal attacks, partisan stereotypes, logical fallacies, and other things that limit our ability to hear and understand one another's perspectives.

However, we have important issues to discuss as a collective, and when we find examples of public discourse where people with differing opinions voice their thoughts and make their arguments reasonably, it's worth looking at. When someone on Reddit asked, "Would limiting the age of the President to 65 be something you’d support? Why or why not?" thousands of responses came in, and the discussion was remarkably civil.

from AskReddit

Considering the fact that the two most recent presidents have been the oldest to ever serve in the office, were both well past the average retirement age for Americans when they were elected, and both had their cognitive abilities publicly questioned during both of their terms, the question of upper age limits on the presidency has become more relevant than ever. Hopefully, this discussion will offer some good food for thought as the average age of our politicians at the federal level still sits close to retirement age.

YES—arguments for presidential age limits

The folks who advocate for an upper age limit on the presidency cite the greater possibility of cognitive decline as people age as one reason, but that's not all. Some point out that the people making decisions should be the ones who will have to live with them long term and that politics needs fresh ideas and perspectives. Some point out that the chance of a president dying in office increases with age, and some say it's only fair to have an upper limit since we have a lower one.

Here are some of the affirmative responses:

"Yes, if there is a young age limit then an older one is justified as well."

"I’d support age limits for all politicians. Asking someone to live a while in the world they create is a fair ask, in my opinion."

"I recently read: 'Someone whose time left on this earth is best measured in years should not make decisions with an impact over decades.'"

"I think the young age limit is bulls--t anyway. We need more people in power who'll live long enough to experience the outcomes of their decisions."

"There is a minimum so a maximum makes sense. 35-70 seems reasonable. A 70 year old running for election would finish the term at 74, maybe 75 depending on time of birthday of course. Just for discussion sake."

"If the average US citizen dies at 74-76 and retirement age is 65 then the max age to be elected should also be 65. I know humans can live well past 100 but the US culture of health spits in the face of aging gracefully."

"I think the dilemma is that experience grows with age but so mental abilities decline. Finding that point where the mental decline is no longer acceptable is tough. Especially with a role like the presidency where really you should be relying on the expertise of other.

Still I support a max age limit. And you could let the older more experienced politicians work as advisors if they want. They don't have to get out of politics but they do have to let someone younger have the final say in things."

"People should be retired from politics at retirement age. As in you can’t run for office after you hit retirement age. And while we are at it, lowering retirement age back to 65 sounds great."

"As someone who actually interacts with 70 year old people, I can honestly tell you the mental 'slow-down' really doesn't start until the late 70s or early 80s.

65 is a little too safe but I would absolutely agree with not being able to run past 70. That would make the oldest member of the exec/leg branches 74. Five years might not seem that different but that's what I'd choose. Granted, I'd definitely support 65 over there not being an age limit.

SCotUS, on the other hand, should be forced to retire at retirement age, whatever that is. I feel that each of them needs to have more of their finger on the pulse of where the country is, due to their more impactful position; 1 of 9 vs. 1 of 100/435."

"75 by Election Day I would support 100%. I would almost definitely support 70 by Election Day."

"Agree. 75 by election day is fair. I work in healthcare and people over 65 should have an opportunity to be represented because they have a drastically different set of needs than people who are 55."

"I get that many people are able to work effectively at advanced ages, but there is a difference between being a professor, insurance agent, or retail worker and being President of the United States. Warren Buffett waited until an advanced age to retire, beyond what most corporate boards would tolerate, but Berkshire Hathaway doesn't have any nuclear warheads. Presidents Reagan, Biden, and Trump have all shown signs of age-related cognitive impairment while in office without any 25th Amendment action being taken, so we need some sort of additional safeguard."

"I support age limits for both physical and mental wellness reasons; 75 by Election Day seems reasonable to me, just because it would have to be somewhere. If nothing else, after 75 the chances a president will die in office go way up, and it’s always better to avoid that."

"Yes. Regardless of one's ability to perform, new ideas need to come into government. The added bonus of weeding out people who have aged out of their competency is second."

"Absolutely yes. They should be young enough to have to live with the consequences of their actions."

NO—arguments against presidential age limits

The people who say there shouldn't be age limits cite the fact that cognitive decline or impairment is not guaranteed with age and that plenty of older people are sharper than people many years their junior. Some cite the need for people of all ages to have representation, including the elderly, and others point out that a long life an experience can be an invaluable asset in a world leader.

Here are some anti-age-limit arguments:

"No, I've met people in their 50s who would be too incapacitated for the job, and yet met people in their 90s who would be. As long as they are mentally fit then it's fine."

"No, because that's ageist, and elderly people need representation too. Our issue isn't the fact we have presidents over 65 years old; the issue is we keep voting for presidential candidates(even in the nominations) that are over 65 years old."

"There is a pretty wide range on health from individual to individual. In theory voters should be able to judge whether the person's health is a concern. That of course assumes transparency on candidate health though."

"No. The issue is mental decline, not age. Different people experience mental decline at different ages. Some lucky people don't experience it until their 70d and 80s. Let the people decide who is fit to serve by our votes."

voting, elections, electing the president of the united statesSome argue that the voters should decide whether a candidate is too old at the ballot box.Photo credit: Canva

"Why? Just vote for a younger candidate next time. You're literally advocating for limiting your own democratic choice... Why?"

"Age ain't always about the number, ya know? Like, got some folks in their 70s sharper than a fresh pencil and others in their 60s feeling like grandpa needs a nap. Suppose depends more on the energy and ideas they bring than digits in their age. We gotta vet 'em on their vibe, not just the year on their birth cert, IMO."

"No. I know too many people over 65 who are some of the smartest and hardest working people I have ever met. It's not the age. It's the attitude and ability.

And the experience in a lot of cases. The type of experience matters. If you have someone with experience making the lives of others better - they will continue to be able to make the lives of others better, even if they are in their 80s (see the notorious RBG). If they have experience with bankrupting companies and not paying their bills, they will continue to be able to bankrupt companies and not pay their bills even if they are in their 80s.

I know more folks over 65 (heck, over 75) who want good education and national healthcare and guaranteed parental leave and higher minimum wages than folks under 40."

"No. It's not going to change the quality of candidates and it's an arbitrary cutoff. People can get dementia at 50."

"I don’t know that age limits are fair. My mother-in-law is 90 years old and she is sharp as a tac and still in great physical health, believe it or not. Not that she’s interested in running for president. Lol. However, competency tests may very well be in order. I could certainly get behind that."

"No. The president needs to have experience, a long knowledge/understanding of current events domestically and geopolitically, and a deep reservoir of alliances, leverage, etc. for getting things done at home and negotiating on the world stage. Biden, for example, had served in Congress forever and was remarkably effective at getting legislation passed despite Republican blockades: a lot of this effectiveness was due to Biden, Pelosi, Schumer's long experience and behind-the-scenes understanding of how to get things done.

I agree that we need more young voices in government but there is ENORMOUS value in having some representatives who are long-entrenched and have an infrastructure and savvy to harness.

This is especially important for diplomacy, which is arguably one of the President's most important jobs. Biden, for example, had been actively involved with foreign affairs for decades and the value of that cannot be understated. Ukraine owes a great deal to the fact that Biden, his cabinet, and his intelligence agencies outplayed Putin at the outset of the invasion, and to the fact that Biden was on a first-name basis with so many world leaders, who he called upon personally to unite with sanctions, Ukraine aide, etc.

Frankly, a young president who only knows of the Cold War from history class would get eaten alive by Putin at the negotiating / leverage table. How can you be taken seriously interacting with world leaders if you were still a kid when they were fighting battles and moving world politics?"

"No. If someone spent 20 years as a teacher, in the military, being a doctor, etc before getting into politics and then got the experience to actually make a run, they’d probably be in their 60s and we could miss out on a genuinely good candidate who wasn’t a lifelong politician. But I would say the oldest I’d prefer would be voting for a 70 year old for their re-election as president. I’d prefer they be younger, but if they’re a good leader I wouldn’t say no over their age at that point. But by 75 they should have no business trying to run the country."

"Personally I want term limits for all branches of government and routine cognitive tests for people 65 and over. I do believe older people should be represented because ageism can exist. As long as you are sharp, you should be able to work."

"In and of itself an arbitrary age limit is meaningless. What we need is yearly cognitive tests with mandatory independent verification and publishing results."

"Absolutely not. While some people have significant cognitive decline past 60, plenty do not. Politicians don't need to have the reflexes of a pilot or motor skills of a neurosurgeon so citing other mandatory retirement ages doesn't follow. We'd be removing decades of experience for potential candidates. Solving the problem of entrenched politicians and stagnating perspectives is going to be much trickier than adding an age limit."

What would it take to put an age limit on the U.S. presidency?

The eligibility requirements to become president are set in the Constitution, so it would require a new constitutional amendment to add an upper age limit. That means two-third of Congress in both the House of Representatives and the Senate would have to vote for it, and then 38 out of 50 state legislatures would have to ratify it. The chances of those majorities agreeing on anything of that great a significance is highly unlikely, but the same could have been said for many of the amendments we've passed in the past. But it's hard to say if a presidential age limit is even something most Americans really want, which is why seeing the pros and cons being argued is so interesting.

Science

People are dumbfounded when they learn this little known secret to burning candles correctly

There's an art to avoiding the "memory ring" that makes a candle tunnel around the wick.

The "tunnel" that often forms around a wick isn't supposed to be there.

The evolution of candles from lighting necessity to scented ambience creator is kind of funny. For thousands of years, people relied on candles and oil lamps for light, but with the invention of the light bulb in 1879, fire was no longer needed for light. At that time, people were probably relieved to not have to set something on fire every time they wanted to see in the dark, and now here we are spending tons of money to do it just for funsies.

We love lighting candles for coziness and romance, relishing their warm, soft light as we shrink from the fluorescent bulb craze of the early 2000s. Many people use candles for adding scent to a room, and there are entire candle companies just for this purpose (Yankee Candles, anyone?). As of 2022, candles were an $11 billion business. Michael Scott once said they're the number one fastest growing product in the scent aroma market.

With their widespread use, you'd think we'd know a thing or two about candles, but as it turns out, a whole bunch of us have been burning candles wrong our entire lives without knowing it.

A recent post on Twitter X started the education session:

"Just learned that my fiancé, who buys candles all the time and we literally always have candles burning, did not actually know how they work and blew out a medium first burn candle 30 minutes after I lit it when I wasn’t paying attention and ruined it," the user wrote.

Many people had no idea what she was talking about. In fact, the original since-deleted post went viral with hundreds of people asking: Huh? So the OP explained.

"If a candle is not burned for long enough on first burn to melt edge to edge it will create a 'memory ring.' Once a candle has a memory ring, it will continue to tunnel and never burn all the way across."

Now THAT'S something almost everyone has experienced. Candles are pretty expensive, so it's frustrating when all that delicious-smelling wax gets left behind. Apparently, a short first burn (in this case, just 30 minutes) is one of the main culprits of a ruined candle.

Tunneling is the name of the phenomenon where a narrow tube-shaped area of candle continues to burn deeper and deeper, leaving lots of "waste" wax around its edges. Experts agree that the first burn should last 2-4 hours at least to avoid an uneven or narrow memory ring. (But don't burn a candle for over 10 hours at a time or you risk too much carbon buildup on your wicks.)

"If a candle is not burned for long enough on first burn to melt edge to edge it will create a 'memory ring.' Once a candle has a memory ring, it will continue to tunnel and never burn all the way across."

"This is why you should not light a large candle at night, which is unlikely to burn all the way across before you need to blow out to go to bed. Allow at least one hour per inch of candle width," she went on.

So that's why candles always end up with a hole in the middle, making us think the candle companies are just running a scam to make us go through candles faster. Nope. It's user error, and many people were flabbergasted by this realization.

"This is the most useful information I’ve been given my entire adult life," wrote one person.

"This skill should be taught in schools," shared another. "The amount I’ve wasted on half burnt candles is outrageous, the amount of times I’ve used Algebra since leaving school = 0."

"When I worked at Pier 1 in the 90s I got to go to some candle workshop that taught us the correct way to use (and therefore sell) candles and that is probably some of the most useful knowledge I've carried in my head this long life," shared another.

Well, never say 'never,' because here's the good news: a tunneled candle can be fixed!

Probably the easiest way is to avoid tunneling your candles in the first place by burning them long enough upon first burn to liquify the entire top layer of wax. Again, that's usually 2-4 hours.

It also helps to care for the wicks regularly! Good wicks allow for a clean, even burn. Trim the burnt ends before lighting the candle and, if possible, use a snuffer instead of blowing out the flames with your mouth. Using a candle warmer is another way to get an even melt; with the added perk of making the scented wax last much, much longer.

But even if you do accidentally "ruin" a candle, it can be recovered. Placing a ring of foil around the candle with just a small opening at the top for the flame will help trap heat and help the edges of the wax melt on the next burn. Once the memory ring evens out, you can burn the candle like normal again.

(In fact, you can even use a candle warmer to melt the wax back to even and then resume burning. Some clever candlers even put candles on the hot pad of their coffee makers as a DIY hack.)

The candle posts also prompted a separate discussion about candles and indoor air quality and the volatile organic compounds that are released when they are burned.

Some people equated burning candles with having a small engine running in your living room, though according to the Cleveland Clinic, there's scant evidence that the amount of toxins released by burning candles is actually hazardous to your health, especially if you use high quality candles in a well-ventilated area.

How do you know if a candle is "high quality"? First, check the wick for metal. Lead in wicks is not nearly as common as it used to be, but best not to risk it if you find metal in the wick. Second, choose soy, beeswax, palm or coconut wax candles instead of paraffin, which is petroleum-based product and more likely to put off soot and smoke particles. Everyone reacts differently to different amounts of particulates in the air, so if you find yourself getting headaches or respiratory symptoms when using candles, it's probably best to avoid them.

But if you tolerate them, feel free to enjoy as recommended,—just make sure that first burn melts the wax all the way to the edges to avoid the dreaded tunneling.

An image of a great glider

When a team of Australian researchers started checking the high-tech boxes they'd installed to help save endangered greater gliders back in 2023, they weren't sure what they were going to find. The hope was that the tree-dwelling marsupials would use them for nesting—a replacement for the tree hollows they normally nest in—but no one knew whether or not the creatures would take to them.

So when Dr. Kita Ashman, Threatened Species and Climate Adaptation Ecologist at WWF-Australia, found a glider in the second box she checked, she was thrilled.

"I just burst into tears, I was so surprised and so happy," she told ABC News Australia.

Greater gliders are nocturnal marsupials that live in old-growth forests of eastern Australia. They have large ears, fluffy fur, long tails, and they can glide up to 100 meters at a time. The species is only found in Australia.

- YouTubewww.youtube.com

"I grew up looking at greater gliders all throughout the Dandenong Ranges. So they have a really special place in my heart," said Dr. Ashman told ANU.

The special nesting boxes were designed and created through a partnership between Australian National University (ANU), Greening Australia and the World Wide Fund for Nature-Australia after 2019-2020 bushfires destroyed a third of the greater gliders' remaining habitat. The tree hollows that greater gliders rely on to nest can take over 100 years to form, according to ANU, so it's not like they can just find some new trees to live in when their homes are destroyed.

Nesting boxes that are commonly used for wildlife aren't a good fit for greater gliders, as the thin walls and lack of thermal protection can result in gliders overheating. (Heat-stressed gliders will slow their eating, which can be life-threatening, according to ANU.) The high-tech boxes in this project are insulated and include a non-toxic, heat-reflective, fire-resistant coating to keep gliders safe.

"I've affectionately been calling this design the Goldilocks box because we hope it will keep greater gliders not too hot and not too cold and will help to increase the species' resilience in a changing climate," Ashman said in July 2022.

"Producing and installing high-quality nest boxes is costly," added ANU research fellow Dr. Kara Youngentob, "so this project is very important because it will help us understand if expensive interventions like nest boxes are the best use of funding in our urgent mission to save greater gliders."

It appears that their efforts are paying off.

"What we didn't know was whether these boxes worked and whether they have an impact on the glider population," Dr. Youngentob told ABC News Australia. "Much to our delight, within a few months of them going up they are already being used by gliders, so we know the individuals themselves like them and use them."

According to Youngentob, greater gliders are the largest gliding marsupial at risk of extinction. More than 200 nesting boxes have been installed in Victoria's East Gippsland and in Tallaganda National Park in New South Wales. Youngentob told ABC News Australia that this project will help researchers learn more about how many of the species are left in the wild.

The quiet, nocturnal marsupial faces threats from climate change and deforestation in addition to the wildfires that ravaged Australia in 2020. Their population has fallen by 80% in the past 20 years and the species has maintained an endangered status since July of 2022.

"They're a treasure for this country." Dr. Youngentob told ANU. "And I think the more people know about them, the more that they will fall in love with them and want to protect them too."

Animals & Wildlife

Why have we domesticated some animals but not others? It comes down to four F's.

An entertaining video explains why we can't ride zebras or breed "war bears."

Horses were domesticated over 5,000 years ago. Zebras, never.

Humans have domesticated several kinds of animals over the millennia, from trusty horses and mules to livestock for milk and meat to our favorite furry companions. But why those specific animals and not others? What is it that led us to those particular choices? Why can we ride horses but not zebras? Why don't we purposefully breed "war bears" to fight for us?

That last question comes straight from the always-interesting and often-hilarious CGP Grey, whose YouTube videos explore all kinds of things we wonder about but don't necessarily take the time to research. In the video "Why Some Animals Can't Be Domesticated," Grey explains the four main elements that make an animal a good candidate for domestication, which excludes bears (and many others) from the list.

Grey alliterated the four elements to make them easier to remember: Friendly, Feedable, Fecund, and Family-Friendly. Let's dig into what those mean.

- YouTubewww.youtube.com

Domestication requirement #1: Friendly

This one is fairly self-explanatory, but basically an animal has to not post an inherent, immediate threat. We have to be able to catch them if we're going to domesticate them, so that eliminates all of the "carnivores whose day job is murder" as Grey puts it, as well as the large, nervous prey animals that are too afraid of us to let us get anywhere near them.

Domestication requirement #2: Feedable

Every animals is feedable, of course, but that doesn't mean it's easy or cheap to feed them, especially in large numbers. This category pretty much eliminates pure carnivores and some omnivores, leaving mostly herbivores (and some unpicky omnivores) that are easy and cheap to feed. And that aren't dangerous (see #1).

Domestication requirement #3: Fecund

This requirement is all about breeding and babies. Some animals are extremely slow to breed, like pandas and elephants, making them undesirable candidates for domestication. Animals that have mate frequently and have relatively short gestation times and/or large litters are more suited to domesticated life. They also need to grow up quickly, which also takes elephants out of the pool.

However, as Grey points out, humans can still tame other animals like elephants. But taming is not the same as domesticating. The basic rule is: If it's on a farm, it's domesticated. If it's in a circus, it's tamed.

Domestication requirement #4: Family-friendly

This is where the horses and zebras question comes in. Horses were domesticated in Eurasia, but if humans started in Africa, why weren't zebras domesticated first? Grey explains that while horses tend to live in hierarchical herds, zebra are more independent with no family structure. Humans can capture the lead male horse and get the rest of the herd to fall in line. Zebra herds are more of a free-for-all and they're kind of jerks to even one another.

horses, zebras, domesticated animals, wild animalsThere's actually a big difference between horses and zebras besides just the stripes.Photo credit: Canva

Barnyard animals have inherent family structures that humans have figured out how to fit into. These animals learn to see the humans who own them as a lead cow or top chicken or whatever.

Way back in the hunter-gatherer age, when humans were just figuring out animal domestication, animals had to have all four of these requirements. Today, we have the ability and technology to domesticate more animals if we want to, but we also have less of a need to. Some breeds of foxes have recently been domesticated, bred to be friendly with humans. How fun would it be to have a pet fox?

Technically, a lot more animals could be domesticated if people really wanted to put in multiple human lifetimes of time and effort, but why?
