 Popular use of the term ‘well-being’ usually relates to health. A doctor’s surgery may run a ‘Women’s Well-being Clinic’, for example. Philosophical use is broader, but related, and amounts to the notion of how well a person’s life is going for that person. A person’s well-being is what is ‘good for’ them. Health, then, might be said to be a constituent of my well-being, but it is not plausibly taken to be all that matters for my well-being. One correlate term worth noting here is ‘self-interest’: my self-interest is what is in the interest of myself, and not others.
