There are terrible diseases married men get.
Most of us are deaf in one ear. Scientists have shown it is usually the side the missus sleeps on.
If this is opposite to the side she sits when giving you directions in the car you can end up deaf in both ears.
A lot of us have thumb prints on our forehead.
Some of us have been horribly mained or killed after replying to the question "Does my bum look big in this?".
Our memory fails us when we are having a "heated discussion" and "She Who Must Be Obeyed" remembers minute and unimportant details from 30 years ago to support her case.
Permanent brain damage has occured when husbands have been forced to sit through a "Chick Flick" because "SHE" want's your company whilst she sniffles though a box of Kleenex.
Instant and severe depression can occur when we first realise that the wife is becoming a clone of Mother In Law.
Seperation Anxiety Disorder is common when we are forced to give up our sports cars and buy a station wagon or similar "practical" vehicle. When you try and explain the kids wouldn't exist if it wasn't for the lay back seats in your sports car the urgency to get rid of it increases. It is like a form of contraception
We have to suppress billions of years of instinct and not notice nice and well proportioned assets on other women. I tried explaining that just because I am on a diet, it does not mean I can't enjoy the menu. That argument made my real menu consist of baked beans on toast for a few days...
So leave us blokes alone. You cruel and heartless Harpies

Black Holes happen when God divides by zero.
