Sorry man...DNA has nothing to do with happiness...just becasue hapiness, their own definition is a ure cultural stuff.. and before going tothe place where geens define what people think hapiness is and saying that DNA fixes wether we think that the term happiness exist.. well.. I am sorry..

Roughly stimation according to my own model of DNA in happiness 0.000005%

Roughly stmation according to my own model of DNArotein netwros interaction (whcih can take cues from the environment and react to it): 1 %

29 % goes to wha tthe definition of happiness (if any) it is in your culture

30 % is fixed by the plasticisy in your brain whcih is fixed the social interaction (mostly when you are a little kid...but you can change it).

15 % is what you eat..

15 % is just pure luck.. poeple that you happen to know, interaction that you happen to have....bad/good things that happen to happen...new ideas that hapen to help yu change your vision of hapines .. and the world..

All this data comes from a very relaible model I once made.

A pleasure

I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
