The only thing is some camp fires don't burn at all, and then other times other types of fires do burn. Also, after more than 200 hours of play I just found out that jumping in a forge was a bad idea - I thought they didn't burn like camp fires.
In my misguided youth, I walked through a camp fire a time or two and did not get burned, so I can see this. Yes, I walked quickly and no I can't remember why I did it. But I had good reason.
Not true! I often swim in Scottish Lochs cold enough to freeze even brass balls (It's a naval term, not rude), and all it does is make your chest hairy and turn you briefly into a woman (might be rude).
You ever heard of the Polar Bear Clubs? These idiots think it is fun to jump into an ice covered lake in January in swim trunks. Of course, they talked me into one year. I really did not think a person could bounce out of the water like I did. I jumped in and either it was a twitch or spasm or something but I remember flying back out of the water onto shore. Which of course was covered with ice and snow and I promptly slid back into the water. Then it was just a mad scramble to get back on shore. Which is why I call them idiots to this day. I earned it.
