From time to time I will edit this OP to graph the poll results. I will estimate the number of posters of any particular age by dividing the poll result by the number of years covered by that poll option.
If your birthday is between August 1 and August 10, you can claim the higher or lower age. It really shouldn't matter whether you found the thread the day it started or the day the poll closed.
Mean and median age estimates, rubber chickens etc will be presented when the poll closes.
