Good health is responsibility of individual?

Good health is hard to define. Mostly, we measure ill-health or death rates.

However, it can be contended that health is partly and individual responsibility: individuals can choose whether to follow healthy lifestyles, for example, or whether to participate in high-risk activities (I was initially thinking of sports, but unprotected sex comes into this category too).

However, good health is also a societal responsibility: developed societies usually have both public health provision (drinking water supply, sewage systems, refuse disposal, etc.) AND healthcare systems. These systems contribute hugely to good health.

The reasons for this are complex, but originate in the notion of healthy workforces and armies and (later) in the idea that it is the state's duty to care for its citizens.
