If you were to walk down the aisles of any pharmacy in America you’d find that one of their most popular products is pain killers. They have shelves that are packed with bottles Ibuprofen, Aspirin, Tylenol etc. If you want, you can buy them in huge jars holding 250 pills. Other shelves contain tubes of "rub-on pain relief" like Ben Gay and Aspergel. Or, you might want to check out various types of chemical ice packs and heating pads. Pain relief is big business in America. We spend billions every year because none of us want to hurt. Everyone wants to live a comfortable life.
