I am forty-something and I don't think I am like any thirty year old...period. I just spent 90 minutes skateboarding and it wiped me out. There is not any sport I have tried that is as dangerous, exciting, or rigorous than street style skateboarding. It is the least forgiving sport I can think of. Let's put it this way, it's not golf. But my age shows, and at best a 40 year old street/tech skater could say they skate and endure like a 35 year old, but not a 30 year old. And I am sure some other sports prove that, too. What do you think?
