"If I'd known I wuz gonna live this long I'da took better care of myself." We all act like we're Superman, don't we?
When I was about 15, I was going to show some buddies what the mercury in a temp sender looked like. Took a hacksaw and held the sender in my left hand, sawing away with my right. Bells went off in my pea brain when I realised temp senders don't have two long wires attached. Can you say, "blasting cap!"?!!
Rolled out the wires, touched 'em to a car battery. BANG! Looked down at my hands, and apologised to each finger for being an idiot.
