How to fix a broken zipper or separating zipper

How to fix a broken zipper or separating zipper. I am tired of throwing away broken gear bags because i over stuffed them and broke the zipper.
Follow the directions and don't squeeze too hard and this will likely work! in fact this will likely work for Pants, Jackets,Gym Bags, Range Bags, Tents, Backpacks, Just about every thing with a zipper.
