boy in blue crew neck t-shirt standing beside white wooden door

This young boy was shown in the process of properly washing his hands at his kitchen sink, briskly rubbing his soapy hands together under fresh running tap water, in order to remove germs, and contaminants, thereby, reducing the spread of pathogens, and his ingestion of environmental chemicals, or toxins. Children are taught to recite the Happy Birthday song, during hand washing, allotting enough time to completely clean their hands.
