38 now and all done

It may have been a bit young, but I'll only be 45 when my oldest heads off to college. I like that Im not to old to enjoy them and I will still have MANY years to travel and relax after they are gone. I know some guys having their first at 40, 45 etc. They will be in their 60s+ when the kids are teenagers. That doesn't sound appealing to me, lol.
