Most things have already been stated, so I'm just posting to add support.
I'll be 40 in January. I too stopped both skateboarding and snowboarding for along time (idiocy) but I started both again and I was instantly in the park. I have been on the snow again for about 5 years and skating again for only 2-3, but I am now a skateboard instructor (I was sponsored by a shop when I was a teenager).
Again, just wanted to give you a summary of my story to provide some motivation.
