Chances are that when you were growing up, your parents had a bottle of rubbing alcohol somewhere in the cabinets or bathroom that they broke out for first aid purposes, and you undoubtedly pass the bottles at your local pharmacy while on the hunt for other things. But did you know that rubbing alcohol is incredibly versatile and can be used for a whole host of household and emergency situations beyond simply sanitizing that scraped knee?

While most of us know that we need to schedule routine maintenance for our cars and even our heating and A/C systems before they break down rather than waiting for disaster to strike, sometimes we're not quite as conscientious when it comes to our own health and well-being. Sure, we might undergo an annual physical each year, but unless we're complaining of any particular symptoms, such a checkup might not amount to much more than a weigh-in, a stethoscope to the chest, and maybe a hammer to the knee to check if you're still alive and (literally) kicking.
