My Two Cents

On Oscar Pistorius.

I don't know if he was so wired he shot his girlfriend in anger or by accident- but either way the man had some major stress hormones circulating for many years- demonstrated by a history of  self-righteous, impulsive aggression.

There's just no way that a double amputee becomes a world class runner without a boatload of dopamine in his system...
Just putting on those legs surely caused tissue trauma.
And I'm sure he fell on a regular basis while training.

Injury seeking is a hallmark behavior of autoimmune OCD.
