Ultimate Fighter Season 6 winner and UFC fighter Mac Danzig exemplifies this. Check out his excerpt in the excellent documentary "Forks Over Knives" -- and here's hoping that more athletes follow Mac's example.
"I remember being 13 and seeing a truck on the interstate filled with pigs all headed to the slaughterhouse. One of them made eye contact with me for a while. It was one of the saddest moments I can remember. There was so much intelligence and spirit in him, and here he was, being sent to an awful death."
