And what he famously said is, I'm not thinking about where the puck is, I'm thinking about where the puck is going to be. Right, right, right.
Oh, that's very interesting. So a lot of what I've studied in my career has to do with time, our perception of time. And the bottom line, of course, is that we live slightly in the past. Why? Because it takes time for signals to get, you know, processed and integrated, right? So when signals hit my... For example, I used to play baseball and...

You know, when you're swinging at a fast pitch, this all happens unconsciously. The best you can do as this ball is traveling from the mound to the plate is to adjust your swing up or down as you're already swinging. But all this is happening unconsciously. My experience has always been when I hit the ball... I become aware that I have just hit the ball.

And I say to myself, throw it out the bat and run. Because it's already flying. The reason being, of course, because it takes at least half a second before you get conscious awareness of anything. The signals have to move around in your brain. As you know, signals are very slowly in the brain, about a meter per second on unmyelinated axons, maybe 10 times faster than on myelinated axons.

It's 10 times faster? Yeah. Okay. And what's interesting, we've got big bodies, right? So if I touch your toe, the signals have to travel all the way up. you know, up your leg and up your spinal cord to your brain. But here's the weird part. You know, if I touch your toe and your nose at the same time, you'll feel those simultaneously.

You know, if I touch your toe and your nose at the same time, you'll feel those simultaneously.
And that's weird because how does your, you know, does your brain feel the signal from the nose and then say, okay, I'm just going to wait and see if anything's coming up. If your eyes are closed? Yeah. Yeah. That's weird. Yeah, so here's the thing. Yeah, yeah, that's weird.

This, by the way, led me to a hypothesis some years ago that taller people live further in the past than shorter people because your brain has to wait for all the signals to come together, your vision, your hearing, your touch, touch from your toes, all this stuff to come together. It puts together your conscious perception of what's happening right now. And that's slightly longer lag time.

Slightly longer lag time if you're taller, yeah. It's a very funny hypothesis, by the way. So... Yeah, so we live a little bit in the past, and during that time, I totally concur, there can't be free will involved in any of the processing or certainly reflexes, but also ballistic movements that we're doing. There's no possibility for free will to operate there.
