I have to agree in OUR [Cosplay] world there is no limit. however i wouldn't go telling people I work with if it is a stern cookie cut work place. It could have a bad outcome. (meaning don't post it to your facebook).
I'm 30 as well. And my coworkers and bosses know that I cosplay (well it makes almost no sense to them) however some think I'm immature because I don't drink so ... >_> I always say "there are worse things I could pick as a hobby" Cosplay supports the economy :3 in the end just cosplay who and what you like.
... And to answer that question "Yes I live here and have nothing better to do "
