The summary as I understood is that hereditary factors will determine about 40% of your ageing rate. Doing the right things (eating your greens etc) will affect maybe 10-15% of your ageing rate if you're generally healthy. Avoiding the bad stuff (obesity, smoking, alcohol) will drastically affect your healthspan and lifespan.
It's hard to take these men as an example not to care. Who knows what genetic cards they were dealt, and who knows how much luck or invisible preparedness they have with their bodies. The conventional health wisdom you mention is borne of millions more examples and unequivocally points in the direction of keeping your body in as good a shape as possible through your whole life.
