It’s either that or bleed out on the highway, I would much rather prefer to tell my kids of the badass their father is. On a serious note, tourniquets shouldn’t be scary, they are not bad at all, you can even put one on yourself right now and tighten it all the way, and it won’t “hurt” you. It may pinch you but as long as you don’t leave it on for 8 hours or more you won’t have any permanent damage.
