Could be that “pandemic” thing making people a bit more cognizant of mortality.

The people dying of COVID are for the most part over age 70. Many are over 80. This is an age where death and disease are unremarkable.

> for the most part over age 70.

CDC categories don't line up to "70" that well, but there are plenty of younger deaths.

51% are 74 or younger.

33% are 64 or younger.

That's not necessarily what OP's saying. My inference is that OP is suggesting that a constantly prevalent pandemic makes people more likely to think about their own health and mortality in a broader sense than they might if there weren't a pandemic.

The best thing I learned from this article: to calculate a dog's human age, you don't multiply their age times 7 (7x). You use the following formula: ln(x)*16+31 It makes sense, because a 1-year-old dog definitely seems much more grown up than a 7 year old kid.

Anecdotally I'm assuming this equation must be breed-specific because I've had a number of dogs 8+ years old that did not appear to act or look very senior.

I think it has to be because I've heard small dogs age more slowly. Maybe there's a way to adjust for weight/breed that I could find if I were willing to dig through the original research paper.

I've noticed more health and aging related articles on this site. I wonder if its a sign the HN community is getting older. :)

The site is almost 15 years old so it’s possible. People become a little more self-aware as they get older. First you know someone famous that died young from a horrible disease. Next you personally know someone who died from a disease. Then you get older and wonder if the “1 in 3 people” might be you.

I take anti-aging drugs for about 10 years. I heard about them at HN.

Playing around with the numbers a bit, I think it's pretty seriously wrong.

A 6-month old dog is still a child, in dog terms. This formula says they're nearly 20 years old; I'd be inclined to say that the "right" answer is more like 15 years, if not less.

A 1-year old dog is beyond adolescence but is still maturing, but this formula says they're 31 years old, well into adulthood.

A 5-year old dog is in the prime of their life; this formula says they're 56 years old, well into the range of what we'd consider a senior.

A 30-year old dog would set a new world record. (The oldest dog known was about 29.5 years old.) This formula maps that to 85 years, which is old, but not extraordinarily so.

I think you should check the very link you sent because only 21% are 64 or younger. The ranges overlap.

How has that worked out for you? What are you taking?

Right? My yellow labrador is pushing 11 and he's all but indistinguishable from his 2-year-old self, aside from a relatively minor decline in energy.

We call him the Eternal Puppy. We expected aging was going to catch up by now. Still very little sign that it's happening.

If I had that dog's energy, I would never be out of shape.

I think a lot of it is that we're just now starting to get to where we need to be as a civilization for anti-aging to start to become something that not only sounds feasible, but is feasible. I've noticed interest steadily increasing over the last 5 or so years, and think this will be a huge topic in the next few decades.
