I'm posting urls to two incredible videos by competent scientists who could excel in stand up comedy as well.

One is Dr Abraham Morganteler, MD, Harvard University Med School Urologist. He invented Hormonophobia to characterize wide spread fear of testosterone founded on incredibly bad science of 1941, passed on as cast in stone for generations until he evidenced scientific and manly courage to shake the foundations of the urological institution. Any doctor who disagrees has, for me, identified himself as a danger to my wellbeing!
