CRUSHED TO DEATH

The 10 degrees of intensity of passion for another man's wife:

1 love of the eye
2 attachment of the mind
3 constant reflection
4 destruction of sleep
5 emaciation of the body
6 turning away from objects of enjoyment
7 removal of shame
8 madness
9 fainting
10 death

Roddy's tip - avoid the inevitability of number 10 by skipping number 5! It works for me!
