Yes, getting Chicken Pox when you are older is awful. The oldest got it when at age 12 and got really sick. The next at 10 and was fine enough. The youngest at 6 and no trouble at all. I always believed in exposing them when they are young.
I was young when I got Chicken Pox and that's a long time ago.

We had everything that came around. Mumps is another one a person doesn't want to get when they are older. No vaccines then and that's fine.
