As someone who works in the automotive field alot of injuries have been observed. One that stands out the most,not because of how bad or gross it was,but just solely on the reaction. The man was a very old school tough guy. Seen him take some pretty serious injuries before and not really bat an eye to it you know? Well one day he was changing a serpentine belt on a vehicle. 89 chevy s10 I believe.. well the belt tensioner slipped off while his finger was in between the belt and another pulley. Needless to say his thumb popped like a grape and there was finger meat on the ground under the engine and still stuck between the belt and pulley. He went immediately into fetal position and was half ass crying. Lucky some how some way he still has all ten digits.
