Poll: What is your age?

The previous polls asking HN readers their age were in 2009 and 2013 ... based on the article related to the average age of successful founders (https://news.ycombinator.com/item?id=16808737), this one also includes founder/non-founder categories (sorry it makes the poll so long). I also realize that this isn't quite the same question that the researchers were trying to answer.

Please pick the category that describes your status as a founder and click only one of the options below.
