A walk in the woods or going for a swim will never be the same once you read about how painful and traumatic your encounter with an animal can get. Forget about being precise, meticulous, or making the prey suffer less. While food might be on the agenda, some animals kill just for the thrill of it.
Do not lose your breath trying to explain that bear you are at the top of the trophic chain. That crocodile does not care about diet and your percentage of body fat. There is no “Get Out of Trouble Free” card while Nature’s laws are at play.
