I know people who don't take their $4/month heart medication prescription and end up hospitalized.
I know people that when faced with the choice of walking around the block for exercise would rather watch Netflix despite their uncontrolled type 2 diabetes and doctor telling them exercise will keep their blood sugar under control.
In my examples this was a person who had a pre-existing dentist who already accepted their insurance - it was literally just the effort to go they couldn’t muster.
The $4 heart medicine was not insurance related. It was already in their medicine cabinet, they just couldn’t muster the energy to set a reminder to take it (or even take it if their spouse reminded them).
And the last one is purely the trade off between Netflix and a walk.
Those things are cheap in the US now?
