@Walter Hinteler,
walter's joke reminds me of an old joke :
old geezer (could be me) sees his doctor and asks what his chances of living to 100 years are .
doc : "do you smoke ? "
geezer : "of course not "
doc : "do you drink ?
geezer : "of course not "
doc : " do you carouse around with women ? "
geezer : "well , of course not ! "
doctor (desparate) : "why would you want to live for another 25 years ? "
hbg - aka old geezer - but still laughing
