My job is that I have to see a patients while looking at mouth. But I am the healthiest and least prone to disease in my family. One of the biggest reasons why I can stay healthy is that I wash well. I wear gloves to treat my patients, but I always wash my hands clean after I treat my patients. And when I get home, the first thing I do is to take a clean shower from head to foot. I always wash my hands and feet thoroughly after a close outing. The first principle of health is cleanliness. During Covid, I tried to keep my mind and body healthy through stretching and yoga at home because it was difficult to exercise outside. Even if I stay indoors for a long time, I don't lie down in bed except for sleeping time, and I read a lot of books and watched a lot of Netflix movies for my own inner knowledge. I watched a movie with my family and tried to improve each other's relationship. I wish I had played an instrument like a violin at that time.
