11 runs averaging 2 minutes per run. I had a lot of fun wearing one of my two pairs of ultra heavy shoulder length neoprene coated chemical resistant gloves slowly getting every apron I own piled on top of me and then adding the second pair over my mouth and nose for an extra smothering grip. The lead aprons made for a delighfully tight crushing grip. If you want to make me happy make me suffer airless under a ton of lead aprons and gear in a vacbag :P I will have to do more with these heavy gloves and one day soon will have to have a go with just my lead aprons so I can enjoy the thick lead aprons squeezing against my face directly, they smell yummy too!
