Replying to Dads and park

Okay so i was recently skiing with my dad and I was getting kinda of bored so I ask if he mind going through the park. So i told him just to stay to side and dont get into peoples way. So anyway while im going down I see him going towards a jump and i was thinking to myself crap hes gonna hurt himself. but he ends up hucking a 3 (which he calls helicopters) and lands it perfectly. HAHAHA i learned today that my 51 year old dad can still ski likes hes 20. Has anyone else experienced something like this??
