Beware of Desensitization

I had heard about desensitization and I didn't think it was a big deal. It is, it's very real, and it's very scary. The best way I have to describe it is the short animation "Nuggets" by Filmbilder. Something that you enjoy and do often, starts to become boring the more you do it. You cling to it and crave more the more you do it, hoping to feel the same happiness you once felt. Applies to a lot of things. Candy, porn, sex, drugs, even that catchy song stuck in your head. It's also something that you might not understand until you grow older and start to feel a little tired of everything. There might be more to it, but I need to think more about it.
