Yes, I can give you a good lecture on preventing heart disease.
You can begin with a study that came out a couple years ago.
Prevention should require courses and classes. And it should definately be allowed to compete for Medicare dollars not just managing tragedy years later.
You can learn all about prevention in a simple google search if you so wish. However, most people are lazy and do things that are detrimental to their health. The only way to prevent that is to have the government have dictatorial powers over you.
and when you are in the ER with chest pain? Do you want the lecture or treatment
