The majority of a persons health care costs are in the last 2 years of their life. A lot of that is terminal issues that wont get curable or caught in a regular checkup anyways.
A regular check up is done once a year. Costs a couple of hundred dollars. If people arent willing to spend 200-300 on their own health. Or if they dont get something checked out because they dont want to spend some of their own money on their health. Or put money into an HSA or FSA. Then, they lay in the bed they have made.
So you say, until they get a bout of pneumonia, and then you and I are left footing the bill anyway.
