Diabetes is clearly identified by ancient Egyptian writings, and described in detail by Hippocrates in Ancient Greece several thousand years ago. Looks like someone in China even around 1500BC. Among many others. Type 1 and type 2.

Let’s not pretend that we’re doing anything particularly new here, except perhaps in scale.

That's true, but people with type 1 diabetes or genetic predisposition to heart disease will still need these drugs. My father, who is in fantastic physical shape and works out almost every day, has the same cholesterol as me, and I am quite overweight and don't eat well. I can increase my chances of long life with diet and exercise. He needs a statin or he will die young.

But also, if you have a person who needs a statin or what have you because they live unhealthily, and you can extend their life by X years by giving them a pill that costs a few dollars a month, why not? There's nothing immoral about helping someone live longer even if it isn't through lifestyle changes.
