I have a spinal fusion and in my 40's.
Yeah, what Jake said. I've got back issues, joint issues, heck even mental issues ...and I'll be 60 in a few months. I still enjoy WC and hope to train for many years to come.
PS JAKE --lost your number. Call or email me (check my sig. below) -- let's get together and train a bit, or just catch up. I'll buy the beer. --Steve
