22. I'll be 23 in 35 days.
Also, your poll doesn't seem to have a spot for those who are 21.
You've got "Under 21" which implies "less than or equal to 20," and then it goes right on towards "22-31" which again, does not include the 21 age group. "21 and under" would be a better group for the first one, or you could change the second group to "21-31."
Just sayin'.
