children

ok, ok, when is it that as a parent you get to stop worrying about your kids? My son is 41 and he ran in the Chicago Marathon last weekend. We were to receive split times on our email. Well, we received the first 3 but weren't getting a finish time. Where was he? What happened??? Finally he called and was ok and had finished (even though it was very hot). We never received that final email. My blood pressure is now back to normal but I keep thinking that there should be a law where we can be exempted from worrying about our kids after they're 30.
