Odds and luck have been against you, Jerry. I remember another guy here who had bone mets with an undetectable PSA.
If you flip a coin, the odds of heads are one in two; getting heads twice in a row is one in four; three times is one in eight. The odds on the next coin flip of getting heads is not one in sixteen, but one in two.
I don't play the lottery, which is a voluntary tax on people who don't understand math. But in your case and David's and Old Sailor's and Gedman's, I think I'd be playing the lottery and spending some quality time in the casino.
@Gedman, What was the antiseptic prep for your surgery? about 1 in 10 people are allergic to iodine-based products and fewer allergic to chlorohexidine.
