If you haven't had chick pox, it could be a good time to go get it. The trend is that it is really bad if one doesn't get it until later in life. Kids seem to have no problem with it. I didn't get it till I was 17 and it was two days of hell, whereas for a 6 year old it's a one-day deal with essentially no symptoms other than a little rash. I recall hearing that it kills you if you're really old the first time you get it. Maybe you had it when you were really really young and nobody noticed.
