Germs are everywhere, lurking on surfaces that you touch, sit on, or handle. Throughout the day germs, which can live on a surface from two days to two weeks, simply migrate from one place to another. Fortunately, despite constant contact with germs, most people are just fine; Philip Tierno, author of The Secret Life of Germs, notes: “Of the 60,000 types of germs that people come in contact with on a daily basis … only about 1 to 2 percent are potentially dangerous to normal people with normal immunity.”
So what surface has the most germs in your home? Take a look at this eye-opening list (location, followed by number of germs found there):
Toilet seat: 70,000
Kitchen cutting board: 140,000
Laptop keyboard: 300,000
Bottom of shoes: 400,000
Kitchen sink: 500,000
The metal aeration screen in faucet: 1.1 million
Kitchen sponge: 14 million
A load of laundry, containing only underwear: 100 million
