Mankind's ultimate goal is self-preservation of the species.

Everyone's goal is to survive. Not just to survive but also do it comfortably. With that being said won't you survive longer and in better spirit if your surroundings are more comfortable? In your surroundings there are other humans. If those other humans were more comfortable would your surroundings in return not also be more comfortable? Do you see the correlation? You're only doing as good as your neighbor. If your neighbor is a grumpy bastard, your surroundings wouldn't be as comfortable as they could be. In terms of self-preservation would it not be in your best interests to make sure your grumpy ass neighbor was more comfortable? For our sakes and our children's sakes shouldn't we try to help each other out. Because I see alot of selfish people abouts these days. So from now on I'm just going to kill them. with kindness. Your brother neosapien out.

For a bunch of stoners you guys sure aren't very philosophical.

valid points, but IMO you need a balance of happy, unhappy and content people. how would you know your comfortable without seeing or experiencing uncomfort
