Sure, I'm a huge proponent of preventative care.
But we don't read about the 3 pack a day fatties in law school.
We read about the doctors who remove the wrong leg, or leave 3 feet of gauze in the patient's abdomen, or somehow cause brain damage and paralysis to a lady who went in for jaw surgery, or totally screws up infants during childbirth.
People shouldn't jump all over doctors for every little thing. There are inherent risks in medications/surgeries etc. To win a malpractice claim, the plaintiff has to prove that the doctor was negligent in that he deviated from standard medical practices. If it is a fatty who was going to die regardless of who practiced on him, then it shouldn't be an issue. But bad doctors (or maybe even good doctors who do a horrible stupid thing) should have to be held responsible for their actions. Lawyers are subject to malpractice suits too. Yay insurance!
