If you’re getting chased by a bear you probably did something to piss it off and you’re screwed. There isn’t a whole lot you can do. It’s more or less a common rule in life, to not pick on someone that’s bigger than you especially if it’s a 600 lb, 10 foot tall Grizzly bear. The odds of getting attacked by a bear are around 2.1 million to 1 so for the most part you’re pretty safe. Your odds go screaming through the roof when you feed or throw stuff at a bear. To me that’s basic common sense, don’t feed or throw things at bears, but some people ended up winning the Darwin award for that one.
You are 3 times more likely to get struck by lightning than to be eaten by a bear. The only exception to that is Roy Sullivan who got struck by lightning seven times and he probably had the worst luck in the world. One of the biggest mistakes you can make is to climb a tree, cause guess what, bears can climb trees as well. If you’re with a friend and a bear comes running at you it’s usually better for you if you’re faster than your friend. Because bears, like us humans, are lazy and they will probably go after the slower one of you two. You are quite unlikely to encounter a bear while walking in the woods, but if you do it’s always an interesting experience. Take pictures but keep your distance especially if it’s a mama bear and her cubs.
