I don't think I've ever heard so much about people having shingles. My neighbor just got over what her doctor thought was a mild case of it. The woman I work with was just diagnosed with it this week.
I can't for the life of me remember if I had chicken pox. I know I had German measles but that's about it.
You are old like me. We almost ALL had it. You were probably too young to remember (I don't!)
Chickenpox is a WAY more serious disease for adults. If you didn't have it you would want the vaccine!
