Biohappiness, or bio-happiness, is the elevation of utility in humans through biological methods, including germline engineering through screening embryos with genes associated with a high level of happiness, or the use of drugs intended to raise baseline levels of happiness. The object is to facilitate the achievement of a state of "better than well." The concept of biohappiness also has its high-profile critics, including Leon Kass, who served on the President's Council on Bioethics during the presidency of George W. Bush.
