MC excitedly explained to Newbie, "after firing a laser pistol, the barrel is hot enough to cauterize skin within two seconds of contact."
"How hot is that?" Newbie asked.
MC called across the room, "Hey Doc, how hot does it have to be to cauterize a wound?"
Doc shook his head in disgust while searching the cabinets and announced, "Don't try to cauterize anything. You will do more damage than the original wound if you don't understand the science behind it." He resumed searching for some hydrogen peroxide and could be heard mumbling, "...size of arteries, tissue necrosis, infection, necrotising fasciitis. If I'm wounded, just give me a bottle of good scotch, some bandages and maybe a splint. Don't let MC near me when my time comes. I'd rather not go out being tortured by the likes of him.."
"But how hot does it have to be?" MC insisted.
Doc turned around and replied in a dejected manner, "That depends. There isn't a single temperature. Are you cauterizing a paper cut or a stump of an amputated leg?"
