Why do women blame everything on their periods?

Women have a convenient excuse to blame everything on saying that their hormones are uncontrollable. Well imagine amplifying that by a factor of 10 everyday of every week. It's called testosterone. The magical hormone that drives men to be violent, sex-craved animals. Most of us are capable of controlling these urges but at times it becomes too hard to fight back. Men should not be held accountable in these instances of lust and violence.
