I just turned 35 and am planning to go to Selection this summer.
AND go into a guard unit.
I know. I know. I got the lecture from some of my SF buddies....
Stew Smith, trainer to the stars, is my age and says he still goes down to BUDs and smokes the younger guys. The older you get, the longer it takes to recover - ice, rest, and a six pack of liquid asprin. Age means as much as shoe size.
The only thing keeping you from SF is you.
Reaper said it best "Your mind sets the limit."
PS - I am not just planning on going to Selection, I am training to kick it in the ass!
