Cancer is one of what he refers to as the "Four Horsemen" (the chronic diseases of aging - cancer, heart disease, metabolic dysfunction and metabolic syndrome, and neurodegenerative diseases).
His book focuses on a number of changes we can make to reduce our risk of these chronic diseases of aging, one of which is exercise and physical fitness.
I would highly recommend the book to anyone interested in living not only a longer life, but a more enjoyable life in old age.
That is "good physical shape" is the evolutionary norm. These cancers (likely) often increase from a mismatch of current diet + lifestyle vs what our bodies (and minds) rvolved to expect. Our biology did not evolve to be so inactive, carry 30, 40 and certain not 100+ extra pounds, eat so much unhealthy food, etc.
This headline's POV normalizes what is historically abnormal. That doesn't help to address and solve the problem.
If you're looking for similar but more accessible, try "The Comfort Crisis" by Michael Easter. Same general idea (i.e., how today's world is not fitting for the type of world we evolved in) but less into the weeds of the details.
It's so weird to me that people need a reason to be fit. Why would you not want to be stronger?
