Nobody in this goddamned world has ever heard the term "preventative" I swear to God.
You don't brush your teeth when you start getting cavities. You brush to prevent them.
You don't install seatbelts after you've been ejected from your car. You get a car that already has seatbelts and airbags.
Vaccines, healthy foods, routine hardware maintenance (cars, computers, etc), exercise and stretches... You're supposed to do and get things BEFORE you have the problems they solve.
We really really need to get into the habit, as a species, of trying to prevent bad things before they happen.
Take the money and run
