If there’s affordable tech which allows us to see our hearts and other internal organs in real time, would it encourage us to eat healthy?

I don’t think it would help!!! We seem to be a society of “It’s NOT going to happen to me.” & assume that those kind of things happen to everybody else!!! IF you look at the salads most people get now days, a bacon-cheeseburger with fries & a shake would be healthier!!! I watched a man at the salad bar today cover his healthy salad in probably a pound of bacon bits & about the same amount of cheese. There were a few healthy veggies & then he smothered it in thousand island dressing & I do mean smothered!!! It was on a regular size dinner plate, was well rounded & the dressing was dripping over the side of the plate. I would have needed a forklift in order to get it to my table. Then when his wife called, he was bragging about eating a healthy salad.

Doubtful. If the tech could show us the results of our bad habits in real time, maybe.

I doubt it. For one thing, most of us probably wouldn’t be able to discern the good organs from the others

It would certainly change my habits if I can be shown what is happening.

Yes.
The shock images legally required on cigarette packages are working, after all.

Loli beat me to it.
Have you seen EU tobacco labels?

There have been a lot people that never even bothered to get check up regularly in medical office, let alone do it themselves. There are also stubborn people that like to believe that “what can’t kill you will only make you stronger” or something like “I’ve been doing/eating XXX since I was little and I’m still just fine till this day”.

It will only make health-conscious people become more attentive to their own health. Others that don’t care to invest in their own health management will never care.
