Is it possible that our modern lifestyles are at least partially to blame for getting these diseases that need medical treatment in the first place? I.e. sitting in front of a computer for 8+ hours a day might lead to us developing these medical conditions that we must then spend thousands of dollars "fixing" (i.e. often treating the symptoms or temporarily improvement) these things that our work environment caused in the first place? Granted, yes, some things existed before this became the norm, like plagues and whatnot, but I think part of the reason we all need to be treated for medical problems is because of the nature of modern work being incompatible with human biology.
