Been working on the truck for a while, and smashed my hand putting in a new intercooler. Didn't like how that felt, so I pulled it out real quick. Caught the back of my hand on a bracket and tore a hole in the hand leather. I could see my tendon through the hole. Anyhow, had a good first aid kit hanging on the wall. Wrapped it up with gauze and tape and a few stitches later, back to work. So long story short, just thinking how important a first aid kit could be in everyone's garage.
