Replying to Am I too old?

I am 25 have been skiing since I was 8.  Good skier and ski all the time (well on weekends and vacations).  I do pretty much everything, except freestyle/park.  I would like to add that element into my game.  I have wanted to for a couple years, but never really dedicated too much time to it.  I ride Line Chronic Blends and attempt a few things, switch, grabs...now i'm not necessarily looking to be a park-hound.  But I do want to do add elements when i pop off rollers or drops, or jib some natural terrain and if I do happen to head into the park, I want to do something exciting.  Wanna learn spins and rails essentially.

Questions:

Am I too old to start this shit?

Am I too big (6'0", 220 lbs)?

If no on both, where should I practice, park or in my element?

Thanks...n00b
