I'm good at changing lightbulbs, painting trim, wiring light fixtures, reaching the top shelf, that kind of stuff, 'cuz I'm pretty tall.
I can do heavy lifting kind of stuff, electrical, PC, and A/V wiring, network and PC repair, general fixing of things, operation of power tools, operation of rope, minor car repairs, shit like that.
I can alphabetize CD/DVD collections very quickly. I can also count money very quickly. I can do quite a bit of math in my head.
I think I'm rather useful to have around, all in all.
