I think Hollywood seems to hit on a money making film idea and then just make loads of very similar films, doing the idea to death or making sequel after sequel of a particular film.
I can't really think of anything really dangerous that I've done. I used to jaywalk alot in high school. I always used to wander around the not so great neighbourhoods in high school. When I look back now I think, hmm that probably wasn't a great idea.
I guess the most dangerous thing now is going out in the woods during hunting season without an orange vest. Although I do wear one now so..
