Last year I had surgery to reduce the size of my prostate, which was causing urinary problems. The surgeon warned me that he would be sending the cut off pieces to the path lab, and that I should not be worried if the results showed some level of cancer. Apparently at age 80, 80% of men have some prostate cancer, which they often die with undiagnosed, and it wouldn't necessarily need treatment. I'm 81 and the test showed NO cancer at all. And the urinary problems were fixed!
What a good thing my life-long masturbation has been! And that's not counting all the other benefits.
And I haven't gone blind, mad, or grown hair on the palms of my hands.
