When I was studying in the United States, I had a fever and headache one day, and I said I wanted to take some medicine. Then I was given a pill at home, and my head didn't hurt after taking it, and the effect was very fast.

Later, when I got better, I asked my house what was so amazing for me to eat, and she said: painkillers....

Then I saw that my family was often unwell and ate one, which was the same as eating sugar.
