While I think this is a good look at what can lead to a long life, and not just long, but quality life, I wish the authors rather than just prescribing certain dietary and exercise tips, or encouraging us to find our ikigai, took a deeper dive to address the ways Western culture actively prohibits us from finding a similar quality of life.  Many of the aspects of culture in Okinawa do not exist in the US, and with such an emphasis on community as it relates to well being and longevity, it's odd that this book doesn't provide any recommendations on incorporating community relationships in our lives.
