Hey, Vsauce, Michael here. At the age of
18, Carl Sean looked like a teenager,
but it doesn't take long in an old high
school yearbook to find teenagers who
look surprisingly old. These people are
all in their 20s, but so are these
people. This is Elizabeth Taylor when
she was just 17. And here are some high
school students from the 70s.
Did people used to look older? Brandon
McCarthy asked on Twitter and evidence
poured in. People shared photos of their
parents in their early 20s, their dad at
21, their mom at 18 or 19, their dad at
45. One user shared their husband at 27,
and what his father looked like at 23.
And there's pretty much an entire
subculture around how old footballers
looked decades ago. 24, 31, 33, 29,
It's not uncommon to think that there's
something more grown up about the way
people used to be. To look back and
think that people seemed older at a
younger age than they do now. Let's call
it retrospective aging. It doesn't
happen to everyone. People do not and
never have aged similarly. And there's
even the opposite observation that kids
these days grow up too fast. But it's a
popular question and subject of numerous
memes.
So,
is it real? Or is it an illusion fueled
by cherrypicked examples that feeds rosy
nostalgia for a time when people were
tough and didn't have it as easy as you
kids have it now? Well, as it turns out,
both humans today really are aging more
slowly than their historic counterparts.
Changes in lifestyle, nutrition, smoking
habits, health care, early life
conditions, and skin care, particularly
the use of sunscreen are a huge part of
it. By comparing measures of metabolic,
cardiovascular, inflammatory, kidney,
liver, and lung function across time,
researchers at Yale and USC have found
that we are in fact staying younger for
longer than we used to. So, does that
mean that 60 is the new 50?
Almost. Their results suggest that
between the early 90s and the late
2000s, 60 became the new 56, 40 became
the new 37 12 and 20 became the new 19.
Oh, also during the last century,
dentistry and orthodontics have played a
huge cosmetic role in the kinds of faces
we see in parts of the world. But
interestingly, when faces in magazines
are measured from the 1930s to today,
the only significant change has been
that across all ethnicities, the media
is now exposing us to larger lips. Also,
retroactive aging can occur over short
time spans. When I was a freshman, the
seniors in my high school seemed so old
to me. But by the time I was a senior
myself, I looked in the mirror and at my
peers and I was like, we're them now,
but we don't seem as old as they did.
What's going on isn't just about bodies.
First of all, the seniors I looked at
when I was a freshman truly were older
than me at that time. They graduated and
went away. And later when I was a
senior, I saw myself as I was. But in my
mind's eye, I saw the earlier seniors as
they appeared to me when I was younger.
Retrospective aging seems to also be
about perspective.
Let's go back to this tweet. This is
George Wint playing Norm on the TV show
Cheers. Now, when Cheers premiered, went
was indeed 34, but I looked it up and
this image is actually from episode 24
of season 5 when Wint was 38. So, we're
not comparing apples to apples here.
However, this is an image of George Went
at 34. And Ashley Fairbanks made some
alterations and a good point.
However, here's the rub. These
alterations don't make W look more like
a 34 year old. They make him look more
like a 34y old today.
Similarly, giving the Golden Girls
