Born to be Happy, Through a Twist of Human Hard Wire

The topic of this essay is very interesting and kept me wanting to know more. Before when I saw people who showed lack of interest or grief towards the tragedy or even death of their loved ones or close ones, made me think that they didn't really gave a damn about them or were after something else, maybe their fortune or something. But after reading this essay I understand now that there are people who have hyperthemia character and dysthymia. I feel sorry for people who have dysthymia disorder, it wold suck to be depressed all the time. People with hyperthemia disorder seems like they dont really have downside since they happy all the time. Maybe if you mix them their kids would come out neutral? Don't know about genetics much, but wouldnt be bad to try it.
