While I don't disagree with you, you seem to underestimate how strong of an immune system I, and I'm sure many others, have. I'm serious. Shredded my foot from glass in the FOx, had sticks stab the fuck out of me, etc.
I was installing a light bar on my truck a couple weeks ago and smashed my forehead on the hook for the hood and cut my head open pretty good. 1/2"-3/4" gash almost down to the bone. It's completely healed up and fine now. Only a bandaid and bacitracin on it. When I was a kid, I was one of those guys with the pedals on his BMX that had huge steel studs to grip your feet in mud. I jumped over something, lost my footing, and proceeded to rip a 3" gash in my shin down to the bone. Never got it sewed up and just kept it covered with a wrap and anti-biotics and it healed up, barring the giant scar I have.
Honestly if I were going to die, it would either be from pneumonia or an animal attack. Which both are extremely likely.
