I'm going to bang the drum again on one of my pet peeves, which is sloppy and inaccurate language~word usage; especially on this sort of topic.
"Healthcare"
What you do to take CARE of your HEALTH, personal lifestyle choices, is the correct use of the term "healthcare". Proper and nutritional diet, adequate exercise and activity, plenty of good rest(sleep), and avoiding dangerous activities/sports, etc., are what should be considered 'healthcare' or 'care of one's health'.
Medical Care
When your "care of health" isn't enough to save you from health issues, such as disease or injury, then one would seek "Medical Care" via doctor, hospital, clinic, etc. to augment your personal lifestyle "care of health".
Medical Insurance
If you don't have the financial resources to "pay out of pocket" for your medical care, then one seeks to have a form of medical insurance to provide for some to most (or all) of that expense. Of course, the more you want your medical insurance to cover/pay for, the more such insurance will cost you. Or society in general if the medical insurance is via your guv'mint (fellow citizens).
Logic and reason would suggest some practical limits to the coverage provided by medical insurance, to keep costs low as possible. Many of us can understand that if our auto insurance was to include things like tune-ups, oil change and lube, new tires, etc. than our auto insurance premiums(costs) will be much higher than when we are paying for more major episode coverage such as damage and injury due to accidents.
To many here in this thread, and the many other similar ones, use of the term "healthcare" tends to reference any one of the three different concepts which should be labeled in more precise and specific terms. Result is we often talk to cross concepts and issues, and one poster is talking bananas when another poster is talking watermelons; and both thing they are discussing the same thing/concept.
OK, back to your usual channel and programming ....
