Adrenalin and Gore

Adrenalin is a counter-poison.
If you are seriously upset you produce more adrenalin and get detoxified.
Most probably because your body has to throw off a maximum of poisons so that you can function well in case of danger.
After an intense fear you can see your hair turn white. Your adrenalin rush has thrown out a lot of mercury into that hair.
I believe the increased success of gore pictures and TV programs is due to the public's need to detox.
You can't help but notice that there is a parallel between the toxicity of the environment and the need to suffer violent emotions.
Just a hinch.
