There are some things in life that if you take the time to think about them it will just make your brain hurt. This is one of them. Watch this video of 2 black bear cubs who are playing with each other. They tackle, they pounce, they punch, it's adorable. You initially just think it's the cutest thing in the world. That's the problem though. Yes, it's adorable now, but you forget that they are going to grow into full size bears. Once they are that size, it's won't be cute play fighting. It will be trained mauling by a killing machine.

Do yourself a favor. Don't think about the future. Just enjoy how cute this is right now.
