I watch horror movies, nail videos, Ancient Aliens, New Discoveries, and I do mind-sharping tests.
Cat videos, what else?
Just about everything. Music, Body Building, Cars, Photoshop tutorials, Martial arts, Boxing, Movie trailers, Politics, Comedy, Fitness.
Just Relax and have Fun with it.
Mostly how to videos.
Like how to shoot a bow and arrow, how to fix a clock, how to do wood carving, how to instal a trailer hitch, etc.
