“Typically, the most aerobically fit people lived with chronic illnesses in the final five years of their lives, instead of the final 10, 15 or even 20 years.”
Of course they can’t disentangle cause and effect, as “aerobic fitness is partly determined by genetics, and to that extent, the luck of the universe.”
Still, “much of a person’s fitness, especially by middle age, depends on physical activity, Dr. Berry says speculates”
Fortunately, a moderate (rather than an insane) amount of exercise is best.
Thinking about this is exhausting. I’m going to go lie down now.
