Often when people near the end of life, secondary to an illness, they
begin to contemplate their lives and recognize that of all the things
they've accumulated and all the accolades that have been bestowed upon
them, nothing is as valuable as life itself.
Certainly both the individual and society have something to gain by having healthy components. Neither of them benefits by simply expecting the other to take on the whole responsibility. Therefore, it is reasonable to conclude that an individual should take at least some responsibility for his or her own health and society should serve as a safety net.
