I'm 40, and I'm pretty sure I could kick my ass at 21, because back then I was 100% TaeKwon Do only, so if I fucked with me I would just take me to the ground and choke me out. That'd teach me!
lol.
Don't say I didn't warn me.
I turn 50 in a couple weeks. I thought about winding my training down a bit. Instead in addition to expanding the 10 p program here, I'm in the process of going live with Bang's Thai program. So besides just rolling with a room full of killers ( many of whom are semi/pro mma fighters and Marines ) I'm now playing smash mouth more than I did in my 20s. Rocking chair will have to wait.
