Sure, I was totally into the monster models. I also built model cars, planes, tanks, whatever. Like all good pyromaniacal teenagers, I eventually blew them all up with explosives.
I still have scars from my Xacto knives, and I think I probably have braim danage from sitting at a table for hours with all that Testors glue and paint (probably worse than all the things I smoked/ingested in college).
