Share your thoughts on the matter

Followed the link you

Followed the link you provided to medical field surgical kits, and I realized that I have no idea how to use most of the items they include. It got me thinking -- as a scout leader, first aid is one of my key areas, and I often run across courses in things like Wilderness First Aid. I've never taken them seriously, because I don't take my kiddos that far away from civilization, but I'm rethinking that in terms of preparedness. Knowledge is a key asset, right? I'd love to know your thoughts on the subject.
