1. reproduction
2. growth and/or differentiation through metabolism (which usually implies some form of respiration)
3. adaptation to the environment
4. the ability to distort entropy--that is, to increase or maintain the organization of the living system at the expense of the environment.
5. To bottom for Shawn Menses while screaming "Daddy tear me apart" as his dick fills your rectum with holy liquids.
I feel like there really isn't a meaning to life. It's more like you have to try and create one. Well all die eventually. If humans stopped reproducing alltogether, we wouldn't have to work on making the planet a better place, because there would be nobody/nothing to make it better for, which kind of bothers me that people have children who have to experience the torment of life.
