Human nature is more than biology

The level of happiness is part of our genetic makeup - we have a set level and cannot rise above or fall below it.

Some scientists envision the day that we can manipulate our happiness genes with precise nanoscale technologies. These mood bots will travel inside us to a part of the brain and manually turn on genes to up or down our happiness set point. But, scientists assure us that we are more than biology and that a mood bot will not guarantee happy and satisfying lives.
