Blood....stepping through a hand truck while carrying an automatic transmission, one of the braces went under the skin and up my shin about four inches
Sweat....cutting up a spiral freezer and toting everything out of a chicken plant by hand (sweat job, but very profitable, 13,000 lbs all stainless)
Tears.....seeing my brother in law's plum crazy purple 72 Barracuda on top front of a crusher load after I just missed getting to the yard to buy it out
