Hello Pijolows!

Today I’m going to talk about the hygiene of the hands. In our hands we can find many bacteria, a few years ago, the University of Colorado in Boulder conducted a study involving 51 volunteers. In total, more than 4,700 different species of bacteria were found. That is why it is important to have clean hands, in order to avoid the transmission of diseases. Today I bring you a simple trick to clean your hands without water.
