No secret, I'm colorblind, and it fucks me every which way I turn. From brown vs. black socks, belts or shoes, to blue or purple whatever. If there isn't someone around who isn't colorblind, then it can get real fun real quick with almost anything for me.
Tracking blood in the fall - slow as hell, but we'll get there.
Electricity - we have a 50/50 chance for me to cut the right wire, cover your nuts. Understand the principles, so there are tools that help.
Plumbing - we good.
Mechanical - love it. I can drive or wheel just about anything, but it won't be pretty and there won't be much left of the tires or engine but we'll cross that finish line sliding in sideways if we have to, duct tape and hillbilly rigged if needed. Yep, gonna need that grinder every time I weld.
Electromechanical - I'll fry it every time. Ill pay the man to do that.
Patience - i have always heard of this guy, never met him, don't think I ever will but I work on it daily.
