Clinical neuropsychologist Mario Martinez brings together insights from medicine, psychology, anthropology and spirituality to create biocognitive science. He insists that mind and body are inseparable from culture; that culture determines how we see ourselves in the world and so has a direct effect on our health. He has a special interest in centenarians and explains that genetics is only about twenty percent of their longevity, but that how they live is the major factor. Martinez advises asking yourself, “What can I do today to believe that I’m a good person?” Give yourself permission to be yourself.
