I’ve examined literally thousands of people with colds, flus, and stomach viruses in my time and have caught less than a handful (pun intended) of their infections.
The reason? I attribute it a lot of it to proper hand washing (and a good immune system).
Yes, protective gear, such as gloves, is important, but hand washing is still one of the most effective things you can do to protect yourself against many, many infections—as long as you do it in the proper way.
Here’s a quiz on proper hand washing that I based on facts and the documenting studies at the CDC’s website. To tell the truth, before I read the research, I’m not sure I would have scored 100 percent. Let me know what you score! (I’ll list the questions again at the end so you can count how many you got right.)
