Good for you. Let's form a club of INTP's who don't have hobbies, or don't have many.I just realised I don't have a hobby :/
Oh, sure, used to help organize some of the more hardcore ones, now just a participant in all kinds. Hardcore = heavy on actual history and period technology and skills. EG no air mattresses, coolers, Lost Cause myths, etc.Have you ever been involved in reenactments?
