Alter Ego wannabe

I sometimes wonder what my life would have been like if I had been an adrenalin junkie, or even a natural jock who could pick up any thing and turn it into a fun outdoor activity.
Sure I was a Tom boy when I was younger... I played baseball, climbed trees, broke limbs, foofi slid into dams, swam in tadpole-infested waters,did numerous tricks with rollerblades, had a BMX gang and gained my RESPECT badge from all the guys for either having the most accurate shot with a bee-bee gun or when I won the Dare challenges. I seemed fearless when I was younger.
Then I hit high school and ..well..still climbed buildings, played Dare and took on the fabulous art called Kung Fu.
After school, a few torn ligaments later, I seemed to lose that momentum. I don't know what happened. I always wanted to learn how to surf but after an unfortunate incident long ago, I have always been scared of the sea.
I always wanted to ride motorbikes and get those funky boots but after a few car accidents(none my fault), I ditched that idea.

As I get older I worry I am losing that edge, that thing that pushes the boundries within myself. I seem to have replaced things like skateboarding, skydiving,hang gliding, zorbing and sword combat with things like sewing, couch-surfing, stretching, eating civilised meals with friends and being careful not to slip on ice in winter time. WHAT THE HELL?

As an act of defiance, I have decided to start longboarding in the summer. I hope I stick to this. Truely. I seem to have developed a fear of hurting myself and not being able to teach Pilates as a result. I think it's a small excuse actually and I am puzzled as to why I have this new found phobia of fun. Or am I just getting far too old? SOMEONE, anyone, please snap me back to reality.
