Hibernation Helps Bears Heal

“To test the healing ability of the bears, the zoologists proved they were willing to risk it all in the name of science. They gave small cuts to the skin of a group of wild bears they were observing just as the bears were preparing for hibernation. Then they backed off and let them hibernate for two to three months. As the bears were reaching the natural time in the season when they wake up, the brave bear researchers checked the wounds. Not only had every bear healed itself, the skin had sealed up with little visible damage and even started growing new fur.
