Thanks. Westreich wrote another recent article that implied the "slightly overweight people survive better into old age" numbers are skewed by the fact that many underweights are fighting chronic disease au priori. I'm still waiting for someone to arbitrate the elderly "muscle-mass vs anti-inflammation" debate (evidently anti-inflammatories work against buidling muscle mass). Can/should one do both? Either way the BMI thing may give way to body fat %, as you say. My articles: https://medium.com/p/f2a7023ed136

Funny how I'm starting to get a lot of my health info from body builders (like Medium's Dr Hunter), I was never into that earlier in life.

PS-I bought a home BP thing too, and its all over the place. I've learned how to game all the tests so that Kaiser stays off my back!
