Health experts recommend you wash your hands with soap and hot water for at least 20 seconds. This is especially important during flu and cold season (at its worst from November through March). Who actually wants to count to 20 while washing their hands? A doctor once told me that 20 seconds is equal to singing the alphabet at a reasonable speed...now I sing it in my head every time I wash up! Definitely a good trick to remember for sickness-fighting hygiene habits!
