And to this I’d add have your children (in matrimony) while you’re young too. That way they will be financially able to take care of you when you can’t.
Well that is a risk. I see too many parents dumped in some horrible old age home. Horrible conditions. Terrible. But you are right it could help to have children when you are younger as long as you can take care of them correctly. My wife and I had my first at 28 almost 29. I think personally that was perfect. My sister had her first at 25, but my brother and sister in law waited seven years after marriage to have theirs at 35. I think that as long as you have children your chances are pretty good that you will be looked after...fingers crossed. lol.
I've said that you oughta start having kids about 30. Old enough to have some kind of established career and financial support, yet young enough to have the ENERGY it takes to raise them properly. I had my first kid at 40, and boy, does he make me feel 60...
