Movie star George Clooney has given up his party lifestyle because he hates hangovers. The Oceans Twelve actor now turns down invitations to celebrity parties and events after realizing he has to take better care of himself, especially since he had back and neck surgery in 2005.

He says, "I don't live at full tilt the way I used to. You begin to hate waking up with the kind of hangover you get from going on huge benders with your buddies. Also, since my neck surgeries, I've been forced to take things easier and not beat up my body the way I used to. I'm more cautious."
