If you have health insurance, then you don't have to do anything. If you've got health insurance through your employer, you can keep your health insurance, keep your choice of doctor, keep your plan.
If 98 out of 100 doctors tell me I've got a problem, I should take their advice. And if those two other doctors get paid by Big Snack Food, like certain climate deniers get paid by Big Coal, I shouldn't take their advice.
My doctor told me that I really should lose some weight. "You're mildly obese," he said. And I thought, "Well, who couldn't afford to lose 20 or 30 pounds?" He said, "Well, a person in your category." I said, "What is that category, doctor?" He said, "Well, you're what I call upwardly middle aged." And I said, "I forgive you for everything."
