You want to think of it almost as a paracrine thing where it has to be delivered into the muscle.

So look, all roads for me still point back to this idea that, and I know you would agree with me, so it's not going to be that controversial, but exercise is the most important drug.

I'm just not aware of a drug

in quotes, that is better than exercise.

And I know there's this enormous effort to figure out a way to put exercise into a pill.

I just can't imagine it'll ever happen.

It's not.

There might be several pills that come out of it.

We might figure out a way to make clotho.

We might figure out a way to make BDNF.

We might figure out a way to deliver IGF directly to muscles.

Like there might be a whole bunch of little things.

I don't know if you remember this.

I'm dating myself, but I don't know if you remember irisin.

Yeah.

Like, I mean, there are no shortage of these things.

Despite all the flack I'm taking, I'm going to just defend this one and continue.

And by the way, if new data emerge, I'm always happy to change my mind.

I've changed my mind about so many things.

It is absurd the number of things I've changed my mind on.
