Have your say about Chris Benoit

Canadian Pro wrestler Chris Benoit suffered brain damage from his years in the ring that could help explain why he killed his wife, son and himself, a doctor who studied Benoitís brain said Wednesday.

Steroid use also has lingered as a theory, since anabolic steroids were found in the home and tests conducted by authorities showed Benoit had roughly 10 times the normal level of testosterone in his system when he died.
