> Let me just put it coldly here: career can be re-established, friend can be re-found, losing family is a painful struggle but it's not impossible to start from scratch. But physical health, once you lose it, you'll likely lose everything else too. The same thing is also true for mental health.

You may want to consider rating mental health higher than physical health. They are correlated, but if in doubt and/or if you need to choose, mental health is the one.

And that's where the social/family component comes in. And the work component. Both contribute to mental health. Just as physical health does. But if work and family/friends "buckets" suck, then no matter how tip-top shape you get physically, mental health will suffer.

Therefore, it makes sense to not place the physical health bucket over the other two. All has to contribute to mental health.
