The Covid-19 pandemic has made many people aware of the meaning of cleanliness. The public is advised to apply the 3M: Wear masks, wash hands, and keep a distance. Every time we travel, we are required to wash our hands and even take a shower to be free from bacteria and viruses. People are also starting to change their habits, such as covering their mouths when they sneeze. This pandemic could be your chance to improve your diet. Food at home is much healthier than food out.
