David MUST be warned of the dangers of veganism!
Besides risking baldness, breasts, sterility, etc - he must realize that irreparable damage has been done to at least one vegans sense of humor - I believe thats spelled "humour" for the weirdo's from the Commonwealth countries - and yes, I am referring to myself.
But I am fortunate - it can get far, FAR worse.
I've seen pictures of one long-time vegan that has been so horribly and completely damaged by the lack of flesh in his diet that he will actually slather some strange substance on his skin, wear nothing more than a hot pink beanie & a skimpy similarly colored thong, and then dance around for hours, roaring & grimacing at anyone who passes by!!!!
I kid you not!
That poor, poor man...
