I am honestly not into the pronoun thing. That is just me so please don't scream at me about it.
I have never had a problem putting my age. And when I tell people my age they don't believe me anyway! They think I am younger. As far as updating it, you do it once a year. Have we become that lazy that we can't do a yearly update when we are doing so many other things online? It takes 2 seconds.
