I've been to two severe wound situations as a civilian - once when I was like 13, the other a few years later
Great video, but as I said in my comment, it's way too clean, and it's NOT attached to a screaming body, that won't hold still. That makes it a tad harder to do in real life - getting 1-2 other people to help hold the person being treated still sure helps
I hope someday to take my EMT classes, but with my health, I doubt it - I will encourage both my kids to at least take advanced first air/wilderness first aid, if not EMT, even if they don't intend to become one
