I am 30 years younger than my father and my eldest daughter is 30 years younger than me. When I think about it, turning 40 doesn't bother me as much as the fact that my daughter will be turning 10. My first 30 years plugged along at a reasonable pace but I feel like the last 10 since I have had kids have flown by. They grow so fast. before I know it, she will be 40 and I will be 70.

So I ask you, by way of easing the potential pain that comes from a milestone birthday, 40 is the new what?
