Once I found out that credit cards were invented (which happened well before I was born anyway -- growing up in the woods tends to leave one out of the loop), I decided that money is pure black magic and ought to be avoided. So no, I have nothing invested in the stock market. Somebody tried to give me some shares of something once, I told 'em to give the shares to Greenpeace and make everybody's life a little more complicated.
My great-uncle Louis, however, was heavy into Enron. Lost about a quarter of a million bucks, or something. Pretty much his whole retirement. Kind of a serious crack upside the grape to a guy in his mid-seventies.
