I actually don't think anything I do is "nerdy". But whatevs.
Besides training MMA/lifting weights/doing cardio six days a week,
here are stuff that might be considered "nerdy":
I can sit with my legs crossed sometimes (hey fk off. tony montana did it in scarface).
I like watching the discovery channe (knowledge is power ya know).
I sometimes write poems (actually haven't done that in two years now).
I enjoy bowling (I'm just a very competetive sob).
Sometimes I actually sing along when listening to music. And somtimes I actually believe I have a good singing voice. Thought sometimes it's crappy aswell. Depends on what song I sing along to.
I'm a HUGE film buff. I know "everything" there is to know.
Also, I spend time posting in threads like these on Sherdog.
Peace, love and a pillow. H.A.jr
