You may think a 'How To' article on sneezing and coughing is a bit elementary, but then you'd be surprised at how many kids (and adults!) fail to take precautions when the cold season is in full swing. After all, it's that time of year when a simple office interaction or playground high-five can spread the funk.

The flu and cold can be given from one person to another simply by not covering your mouth when sneezing. Those pathogen-packed sneeze droplets come shooting out of the mouth at 100 MPH or more. That's 40,000 to 60,000 fluid droplets! It's our responsibility to cover our own mouths when the urge arises.

Speaking of covering mouths, use a tissue. But if you don't have one available, the crook of your elbow works great too. Otherwise, if you blow all that gunk on your hands and extend it to shake someone else's, they could end up sick just as easily! Of course, a sure-fire way to stay as clean as possible is to use a travel version of antibacterial hand sanitizer (like Purell). It doesn't take a lot of effort to ward off the sick season!
