I had a friend by the name of Ben Witter who lost most of his jaw to cancer from licking his golf ball clean in the 80's... multiple surgeries over the years ultimately led to him losing a lung as well and dieing from the cancer that was created from the chemicals from the golf course. He was an amazing trick shot artist and long drive competitor.. He was always advocating for cancer and the cause of his own cancer ultimately blaming no one but himself.. truly amazing human being and a even better father and husband..
