A gene variant associated with being a physically and mentally active individual seems to also be linked with living a longer life!
Scientists found that the dopamine receptor gene DRD4 7R allele appeared in significantly high rates in people aged 90 years old or more. Those who carry this gene are generally more motivated to pursue physical, intellectual and social activities.
This study supports the well documented theory that the more involved in physical and social activity a person is, the more likely it is that they will live a longer, healthier life.
