and its impact on training your body's energy systems is positive, but just the injury rate is taking you out, so you're kind of in the middle.

You're very close to the general population.

Cyclists only have two years on the general population.

And so what I thought was interesting, I think a few things are interesting about that.

So first of all, there's a lot of people in the longevity space

are taking most of their information about how they should train for longevity from people who specialize in cycling.

Really?

Well, yeah, I'm not going to name names, but there's, you know, a lot of people out there who are, you know, that's where it's coming from.

And I, you know, it makes a lot of sense that...

Cycling is, you know, it's good for cardiorespiratory fitness.

There's a lot of data that having good cardiorespiratory fitness is a key factor for longevity.

But when you look at a study where gymnasts and pole vaulters have six extra years on the cyclists and the cyclists only have two extra years on the general population, I'm like, huh?

It's not all about the cardiorespiratory fitness.

And so what I think about, it's an observational study.

You can't prove cause and effect, but it just does make you think.

And the way that I think about that is a few things.

So first of all, the commonalities between gymnasts and pole vaulters, it's definitely not height, because gymnasts tend to be short and pole vaulters are tall.

And so the height cancels out.

Definitely they're fit.

It is interesting that cyclists have a good lower body and gymnasts and pole vaulters have a good upper body.
