Road Safety

"I feel like it is a common sentiment that all semi-drivers are good drivers because they have to get licensed and whatnot."

Staying Warm

"Drinking alcohol makes a person FEEL warmer but you're much more susceptible to freezing to death."

"The reason that it was given to people when they were found freezing was actually because they had been found. And opening up the blood vessels to get blood into the extremities helped prevent frostbite."

"So you could say that alcohol decreases your chance of frostbite, but increases your chance of dying. If you know how long you have until help arrives, you can use this to your advantage."
