One of the things that nobody ever talks about is your body awareness. When you do fitness for a long time, 50 years old, you've been doing fitness - Mm-hmm. - for a very long time, you are so - Mm-hmm. - in tune with that vessel that when something does pop up, - Mm-hmm. - you identify it right away. - Mm-hmm. - When you don't, you're like, "Um, my back kind of hurts." "Where?" "Uh..." You don't know. I'm in tune with that thing so well that when I walk into a doctor. - Mm-hmm. - I'm like, "Take a needle three inches down, rotate it over 45 degrees, and that's where it is." - Mm-hmm. - I'm like, "Okay, this is it." I'm so in tune with it. - Mm-hmm. So when anything pops up, I can diagnose it. I can walk in and give them actual feedback on what's happening.
