I've had 2 back surgeries and I'm only 26 so yeah, injury avoidance is pretty high on my list.
I've had some image issues since i broke my face 8 years ago, so starting physically fit is important to me. Just gotta keep things in perspective. I was pretty happy with things right before i left. I'm sure I'll get back there in the next 2-3 months if i place my cards right.
