British scientists proved people are more likely to wash their hands after using the toilet if they are shamed into it or are being watched.

“Hand-washing is the cheapest way of preventing disease but less than one-third of men and two-thirds of women wash their hands with soap after going to the toilet, a British study by the London School of Hygiene and Tropical Medicine showed,” MSNBC website reads referring to Reuters.

But when electronic message appears on a board asking: “Is the person next to you washing with soap?” more than 12% men and 11% women used soap.
