Not ALL wrestling is fake. Professional Wrestling is fake. Amatuer (high school, college, freestyle, Olympics) is ALL REAL. i know this because i have wrestled in high school and college, coached high school wrestling, and participated in Professional Wrestling for 10 years (1985-1995) and did several T.V. tapings for the WWF( now WWE). don't worry, i wasn't the "star", just the jobber who made the star look like a million bucks in three minutes.
all of that aside, i don't believe steroids caused this, because he deliberately over a three day period killed his family and himself. Roid Rage is associated with a lack of self control, not deliberate premeditated behavior as this seems to be.
Also, Redneck, the blood IS definately real. The cuts are made at the scalp line, where the hair begins so that they are easily covered up. they are just nicks, but head wounds bleed profusely. remember, it is the job of these men to DECEIVE the masses. and they are GREAT at it.
