Well, I'm going to give a different answer because there are multiple ways to answer it.

I think the purpose of life is to do your best with the skills that you've been given every day to make the world a better place for future generations.

And that's how I live my life every day.

Thank you, Stephen.

I really enjoyed it.

Thank you.

Right.

Well, so longevity is the more academic way we describe what we research.

Anti-aging is kind of the same thing, but it's got a bad rap because it's been used by a whole bunch of people that don't know what they're talking about.

So I really don't like that term anti-aging.

But aging as a disease and longevity are perfectly valid ways to talk about this subject.

So let's talk about aging as a disease.

When I started my research, disease here at Harvard Medical School, it was considered if there's something that's wrong with you,

and it's a rare thing, has to be less than 50% of the population, that's definitely a disease.

And then people work their whole lives to try and cure that condition.

And so I looked up what's the definition of aging, and it says, well, it's a deterioration in health and sickness, and you can die from it, typically you do.

So I'm thinking that sounds pretty much like a disease, but the caveat is that if more than half the population gets this condition, aging,

It's put in a different bucket, which is, first of all, that's outrageous because it's just a totally arbitrary cutoff.

But think about this, that we're ignoring the major cause of all these diseases.

Aging is 80% to 90% the cause of heart disease, Alzheimer's.
