@Merry Andrew,
												But that would put that great shaman out of business.  I am never sure of anything that we can't be sure of, but I've lived a good long life by being unorthodox and I've escaped a lot of miserable things in the process.  I may die younger than necessary, but......oh well.  For now it's all good. 
Disclaimer:   I absolutely 100% do not necessarily recommend my choices to anybody else.  And if I had any symptoms of any kind that were alarming to me, I would definitely see a doctor immediately.  And I think regular check ups are a good thing to do.
