And by exercising, I will maintain that and have.

In fact, I probably haven't had a body like this since I was 20.

So that's one of the benefits of having this lifestyle.

I don't want to get too much into the anecdotes, but I'll tell you the science, which is that

If you take a mouse and put it on fasting or caloric restriction up until the point where it should be infertile, so that's about it, at a year of age, a mouse gets infertile, female mouse.

Due to fasting or due to simply to aging?

Due to aging.

Due to aging.

The fasting, it's not an extreme fast.

It's just less calories.

Got it.

Then you put them back on a regular food and they become fertile again.

for many, many months afterwards.

So the effect on slowing down aging is also on the reproductive system.

Interesting.

And so I wouldn't say to any woman, I wouldn't think that they should become super skinny to try and preserve fertility.

That's not what I'm saying.

But these pathways that we work on, these sirtuins, are known to delay infertility in female animals.

Case in point, I'm one of the lead authors on a paper where we used NMN.

Remember, this is the gas, the fuel, the petrol for the sirtuins.
