Important information for the coming cold season...

Step 1.
Use paper facial tissues instead of cloth handkerchiefs. Germs thrive in dark, moist environments.

Step 2
Avoid blowing your nose too hard. Too much pressure will force infectious drainage into your ears and sinuses.

Step 3
Press one finger over one nostril.

Step 4
Blow gently through the open nostril.

Step 5
Repeat on the opposite side.

Step 6
Use tissues once, then throw them away.

Step 7
Wash your hands. Germs will be on your fingers after you've handled your nose and your tissue. Don't spread the germs to other people or back to yourself.

Or there's always the snake option...
