One of my good friends has done many clinical trials with testosterone.

So I think there's a use for it, but it doesn't lead to longevity.

That was very clear.

So for health reasons, yes.

For longevity, no need.

Yeah.

I'm happy to.

What happens to me because I'm a scientist and, you know, I'm part of this ivory tower at Harvard where we can only stick to facts.

And if you go beyond that, it's a crime.

And I've been criticized for that.

But I think, you know, as humans, life's interesting when it comes to predicting the future.

And like you, I'm very curious, where is humanity headed next?

I see a future as different from this world as our world is from 200 years ago.

And that will happen in our lifetime.

Different in that 100 years ago or more, if you had an infected splinter, there's a reasonable chance you could die.

Childbirth, you could die.

Smallpox.

These are things that we don't generally worry about anymore.

And the idea would be abhorrent.

In the future, hopefully within our lifetimes, there will be a time when we look back at today's medicine when you could go blind and there was nothing you could do.
