I'm 27 and I still skate. I'm still in the military, still in college, married, and still paying the bills. What are you waiting for? Dust off those skates.
Been rollerblading for a really long time (since back in 1994) and I still love it. I just wish my body healed as fast as it did when I was a teenager and I wish I had more time to skate now that I'm an adult living in the real world.
