It seems that there is a gene for everything these days, including being happy. According to The Guardian, psychologists at Essex University claim to have discovered a gene that helps people have a positive attitude to life. I must admit that this is one of those occasions when I am deeply suspicious of science reporting in national newspapers, but a gene that helps the body resist whatever chemical malfunction results in depression doesn’t appear impossible.

I don’t think I need to comment further because I can just refer you to Amanda Palmer, who has thought about such things.
