Brain damage?
Nightline is doing a report now on the death of wrestler Chris Benoit, who also killed his entire family. Scientists who have examined Benoit's brain believe brain damage - and not steroids - may be the cause of Benoits depression and subsequent murder-suicide actions. They have also been looking at football players who have undergone similar depression and suicide and conclude that they have similar brain damage. Their brains look like the brains of Alzheimer patients. Yikes.
