you know youre a parkour kid when you monkey vault over you girlfriend when she bends over instead of slapping her butt
i did this today, she fell over though cuz she wasnt expecting it and it made me feel bad.....lol
it was a speed vault though, i cant do monkeys yet

and as for the drop thing, just because youre a "parkour kid" doesnt mean you dont have the ability to take the jump. i realize youre saying this for the health/joint issues but ive been jumping off things since i was too young to remember doing it (my mom has vids of me jumping off of rocks and out of cars when i was about 2' tall, lol)
my body is definitely ready for and used to large drops, though i still dont take them too often because i now know that ive been landing wrong and im trying to perfect my rolls before doing it more....
i used to never roll, but i never hurt myself landing either...
