Yes, that was interesting! But I went huh? and oh yes! severasl times:

- "fit" women, defined as women who walk at least 30 min per day. Is that total activity? We evolved to walk around on our feet all day, didn't we?

- hip injury lead to illness - oh yes, I've watched my mother, who "doesn't exercise" but used to love hiking, get feeble and feebler as her hips got worse. It practically immobilized her and she didn't have the motivation or experience to do other exercise.

- blueberries: Norway's Labour Party's Grand Old Man, Haakon Lie, who is 102 and very much all there, attributes his health and vigour to eating a cup of blueberries every day.

- "Just by vacuuming, mopping floors, or washing windows for a little more than an hour, the average person can burn about 285 calories, lowering risk of death by 30 percent, according to a study of 302 adults in their 70s and 80s." What lowers risk of death by 30 % - burning 285 calories? Housework as such? How about exercise instead?

Yeah, I'm picky, sorry
