I love parkour and started doing various things in that direction recently. I won't mind if my daughter actively practices this as well although I do get worried when she climbs or stands on her head, etc. It's ok to worry and be concerned, but I think we should let our kids be active and develop physical and acrobatic skills. It's all better than sitting on one's butt playing video-games for hours. Great!
