Maybe I'm a bit bias as I am in the health field, but when someone asks for a donation to cure cancer, I respond by asking what we're doing to prevent cancer (i.e cigs, bad food, etc). Why are we spending millions of dollars trying to cure something that we allow the cigarette companies (and others) to foster?
If you keep backing out over a nail in the driveway, should you spend the money by continually fixing the tire, or pay someone to remove the nail?
