George Clooney

Clooney suffered from Bell's palsy for a time while he was in high school.

In 2004, Clooney injured himself on Syriana's set during a torture scene. He had some excruciating headaches and suffered short term memory loss. It took a few weeks for his doctors to find the reasons for his health problems. During The Good German's promotion (two years afterwards), he revealed that he still had to wear a back brace due to this injury.

Never a heavy smoker, Clooney quit the habit at a very early stage. He says that at least eight or nine of his great-uncles and great-aunts died because of it.
