"I would say that good health might be the most important measure of happiness and success."

You made a blanket statement about health being the most important measure of happiness and success. My point is that it's not, or shouldn't be, because it's never a guarantee.

Our society moralizes health to a ridiculous degree. People who are merely viewed as healthy (regardless of even knowing if they are) are revered. Anyone who is perceived to be "unhealthy" is pitied, at best, mistreated at worst.
