To write off the whole sport as stupid is a bit unfair. Just because it is far outside of your comfort zone (and mine for that matter) doesn't mean it is stupid.

These wingsuit wearing daredevils have the chutzpah to plunge into the void and experience soaring like birds.... Probably one of the best feelings a living being can experience. They may be bold, but I wouldn't call them stupid.

I think it's more dangerous than stupid.
