One of my sisters is a paramedic and another one of my sisters is a survivalist who used to be a teacher with the peace corps in some of the most remote regions of the world.
My trauma kit has most of the common items a paramedic would have. So, when it finally happens, I'm fairly proud of some of the items in my kit. And even though I have some weird Zen thing about not getting cut by knives, I still injure myself plenty, so that New Skin has already seen use a couple times. It's basically super glue with an antiseptic.
