Don’t worry—aspirin pills have got some manly uses, like starting up a car with a dead battery. That being said, it might be a good idea to stash a bottle of aspirin in your car, just in case it runs out of juice. If you’re stranded without power, you can drop two aspirin pills into the battery cells to jumpstart the charging. The sulfuric acid in the battery mixes with acetylsalicylic acid (aspirin) to create one charge. It will be enough to rev up your engine and get you to the nearest gas station.
