Well, there's no change.

So what we're looking for, it is a change.

If you were good at something and now you're not, you know, that's the change that becomes worrisome.

If you were never good at it in the first place and you're still no good at it, then don't worry about it.

I'm in the same boat as you, Mike.

It's never been my forte.

If I had to say one single thing, it's physical movement, vigorous physical activity.

And it has to be vigorous.

It's the only known thing that stimulates the growth of new brain cells,

It stimulates the interconnection between existing brain cells, and it increases and balances the what are called neurotransmitters.

which are the chemicals that let the electrical impulse travel from one brain cell to another.
