The majority is somewhere between overweight and vastly obese, which is a choice (even in HN's latest boondoggle of "you lose weight if and only if you are injected the right drugs", obesity remains a choice). Similarly, the vast majority of people don't even meet the basic WHO guidelines on physical activity, which is even more obviously a choice. It is well-known that making these choices precipitates virtually every common, serious disease. Therefore, most people are unhealthy by choice.
