From Wikipedia: Charles Krauthammer is an American syndicated columnist, author, political commentator, and non-practicing physician whose weekly column is syndicated to more than 400 publications worldwide. Krauthammer became permanently paralyzed after a diving accident while in his first year studying at Harvard Medical School. After spending 14 months recovering in a hospital, and although wheelchair-bound, he returned to medical school, graduating to become a psychiatrist involved in the creation of the Diagnostic and Statistical Manual of Mental Disorders III, and later developing a career as a Pulitzer prize-winning writer.

Martial arts instructor Jake Mace tells the story behind his scar and arm fracture:

Mayo Clinic emergency medicine specialist Dr. David Nestler talks about how cold weather affects our bodies and what we need to know about frostbite:



“It’s a shame whenever anyone gets a frostbite injury,” says Lawrence Gottlieb, MD, professor of surgery at the University of Chicago and director of the Burn and Complex Wound Center. “People need to be aware of it and take precautions when the temperature drops, like it has this week. Be especially cautious when temps fall below zero, especially when there is a strong wind. Obviously, wear warm clothes. If you are driving a long way, especially at night, make sure you have enough extra clothes to cover up effectively if you get stuck somewhere. And don’t get stuck. Put enough gas in the car.”

Tips for people who go out in the cold

- If the temperature is below zero you could sustain a cold injury in less than 15 minutes.
- Mittens are warmer than gloves.
- Insulate the affected body part to prevent additional heat loss and damage.
- Immobilize and protect the frostbitten tissues from further injury.
- Prevent thaw-refreeze cycles. Do not begin rewarming until there is no risk of further exposure.
- Once in the hospital, physicians recommend rapid rewarming in a water bath at 104°-107.6°F (40°- 42°C) for 15-30 minutes until thawing is complete.
