Bear Hug: A man once escaped a bear attack when he locked his arms and legs around the bear in a reverse bear hug, which made it confused and it ran off. If you're on your back and the bear is on you, it might be your last resort.
Gag Reflex: Bears, like many animals, have poor gag reflexes. A man recently survived a vicious bear attack by shoving his arm down the bear's throat, causing it to gag and then retreat.
Calm The Charge: While it may be the last thing on your mind, calmly standing your ground when a bear is charging can be the best attack deflector. If you get a bluff attack as a warning, stand, wave your hands, and talk calmly to the bear.
