The Danish Twin Study established that only about 20% of how long the average person lives is dictated by our genes, whereas the other 80% is dictated by our lifestyle. And then lists 9 things that fit with the idea of moving back to the passive solar design vernacular architecture and walkable mixed-use neighborhoods that used to be more the norm before we became victims of our own success and began tearing down SROs left and right and zoning Missing Middle housing out of existence (in the US, at least). https://en.m.wikipedia.org/wiki/Single_room_occupancy https://en.m.wikipedia.org/wiki/Single_room_occupancy

I think we need to also remember that people cannot focus on healthy living without financial security. Financial insecurity forces people to sacrifice health, safety and wellness to make ends meet. Fortunately permissive zoning not only facilitates the emergence of densely populated and walkable mixed-use neighborhoods, but also significantly increases incomes. [1] Other policies that I advocate to this end are a focus on law and order to prevent the emergence of ghettos (Thomas Sowell explains how the 1960s riots and subsequent normalization of criminality contributed to the ghettoization of many inner city neighborhoods [2]), a focus on building public transit and bike infrastructure, and market friendly policies like a light tax burden, and an absence of centralized (regulatory) control over market interaction.

  In the US, walkable mixed-use neighborhoods, more bike infrastructure and better access to healthcare for the masses would be a huge improvement and also reduce financial stress for people of limited means. Those are bits I know. This is not a rebuttal of anything. I'm simply unfamiliar with some of your points.

That heritability was estimated based on Danes born 1870-1900. It's likely that heritability has increased since then because there's less variability in the environment: health care has improved, there are fewer accidents, poor Danes are unlikely to be malnourished, etc. This study shows that heritability is basically zero below the age of 60, but increases a lot thereafter: https://link.springer.com/article/10.1007/s00439-006-0144-y https://link.springer.com/article/10.1007/s00439-006-0144-y
