Devil's Advocate (not just door hardware): It's not all the doctor's fault. Nor is it to blame them as pill pushers. Yes, it's true that if people ate better, exercised and did other healthy things, it would, all else equal, provide much healthier and probably, happier lives. This is simple wisdom and it's not suppressed, and no it's not some evil conspiracy of silence on the part of the medical fraternity. There's a very simple explanation rooted in human nature: the awful truth is that the average patient doesn't WANT to eat well and exercise. He likes his unhealthy diet and sedentary lifestyle. As such, the best doc can do is treat his conditions as they arise, with the tools at his disposal, principal of those being drugs and surgery, and try to help the patient to be as healthy as he can, given the limitations imposed by his poor lifestyle choices. Note: I'm by no means letting doctors off the hook for ALL that goes wrong (medical errors, and horrors like the Covid-19 vaccines, malpractice etc.) But if we face the truth without bias, isn't it fair to say at most, perhaps the vast majority, of our illnesses are self-inflicted?
