The Hook

Did you know most people only wash their hands for about six seconds? But health experts say it takes a full 20 seconds of scrubbing with soap to actually remove the germs that can make you sick.

The Real Talk

The Story

Amara, 12, was at practice and noticed she was sweating way more than she used to. Later, she thought she smelled different, and she got really self-conscious. She started worrying that her friends would notice. The next day, she felt nervous about raising her hand in class. She decided to talk to her older aunt. Her aunt smiled and said, 'Welcome to the club. Your body is just turning on its new cooling system.' She explained that new sweat glands activate during puberty and that it happens to literally everyone. She showed Amara the difference between deodorant and antiperspirant and helped her pick one out. Amara realized it wasn't a weird personal problem; it was just a science thing she hadn't learned yet.
