I worked with a guy years ago who's son did a lot of the bike stunts in the early Mountian Dew commercials. He ended up doing a face plant on concrete, shoved his nose slightly into his brain. He ended up pretty much a veg. Most of them are crazy. But I did see two clips I recognized, so not to still the thunder I'll start a new thread on the side note. It was a fun watch.
When I was young It was sore and black and blue. Now it's down and out, an using a crutch to get around.
Hopefully some of them will still be around when they get old.
When I was young I tested the limits of the human body by riding bareback broncs in rodeos. Did it for a number of years. It has been over 31 years since the last time I crawled over the chutes. But I get reminded of some of those rides every morning when I wake up. I have a feeling that some of these young people will be getting reminders of their stunts in 30 or 40 years too.
