If you ask people to rank say 5 things from top to bottom where the first thing at the top is what they are least cost conscious about and the one at bottom is what they are most - I would bet health would at the top slot for most of us. So relatively we would spend (whatever we have) on our health versus other things if we had conviction on the outcome.

People don't do anything with the data they already have, to your point.
replyStand on a scale at the same time of day, every day. Track your intake. Track your output. See your PCP for your free AWV-equivalent, and keep an eye on your metrics.
But no, we need GB of scanner outputs because some medically-illiterate (but still the smartest-guy-in-the-room) techbros want them for... reasons.
