Man I love watching people do Le Parkour, it is totally rad and I wish I was fit enough/had enough co-ordination to do, like, any of the stuff in this awesome video done by a couple of crazy russians. I dunno how tall (and I guess getting old) guys would be well suited to this sort of stuff, seems like something small ex-gymnasts would do :) .

EDIT: Oh yeah, excuse the arty camera shot stuff from the 1 to 2 minute mark, I thought the video was screwing up but it wasn't!
