EUGENE, Ore. - Cold and flu season is here.

One of the best ways to keep yourself healthy is simply to wash your hands, but a lot of people don't do it correctly. You want to wash your hands for a solid 20 seconds. That may seem like a long time, but a good rule of thumb: just sing "Happy Birthday" twice.

If you do have to use hand sanitizer, one thing you want to check for is how much ethyl alcohol it has: 60 percent is the magic number, but the higher the better.)

Another thing is too much physical exertion. Now if you normally work out that's fine, you can stick with it. But if you're just now getting into exercise, you could be compromising your immune system, making you more susceptible to things like the flu.

If you do get sick, don't spread the disease. Cover your mouth with a tissue if you're coughing, sneezing, blowing your nose, and then throw that in the trash right away, don't leave it out with all of the germs.

You might also consider getting a flu shot.
