Many couples are opting for dogs instead of children. Hopefully, they are saving their money for their old age.
So, you see having children as a means of caring for you in your old age. Don't count on it, Mac. I'm sure that others can recite instances in which the children did not, positively did not, assist their parents when the latter grew old.
I have no children (for which I give thanks every day), and yes, I am financially comfortable in my old age.
P.S. My dog is great company, too.
