"men don't live as long because generally they don't look after themselves as well."
That is called blaming the victim. Try that with a feminist about female victims  sometime and see how far it gets you. Funny how it is ok when a woman, you, blames male victims.
"i don't think the shelters are a female privilege, they are there for the children"
Then how do you explain all the childless females using shelters?
" aren't half the children brought to shelters boys?"
Some shelters don't accept people with a penis no matter what their age, some if they aren't post pubescent and essentially none accept them after 18.
"my husband didn't pay support"
Why would a grown man pay to support a grown woman? If you are talking about child support, did you make 50/50 access easy? Many women don't. They use children as a weapon against their ex. The courts don't care.
"no advantage to me in CPP "
You live longer and collect longer despite having made no greater contribution.
