Body Odor...

When I was talking about ages with my friends, one of my friends told me that after getting 20 years old, people start to produce body odors, that is "Karei-syu" in Japanese. I was quite shocked by her saying. On this September, I will have been 21 years old. So, it means that I have been producing body odor for one year. After I heard it, I hurried to buy a perfume.
