I don't think of it as one day being taken care of by your kids.  I think of it as having family to spend time with when you're old and all your same-age friends have died.

You do realize that "family" includes spouses, in-laws, cousins, siblings, nieces and nephews, right? And that people can make friends who are younger than them?

Having children guarantees none of what you're going on about. And I certainly wouldn't risk destroying my life now in a misguided attempt to try to guarantee some kind of companionship with people who happen share my DNA 40 years from now.
