After the Haircut
It's getting hot. You go to have your hair cut. The barber Tony cuts off part of your hair and sweeps it away, but your hair's journey is not over after the haircut.
Have you ever thought of planting your old hair after it's cut off? Some farmers do! What comes up? Not wigs(假发), but bigger and tastier crops. Hair is full of nitrogen(氮) that helps plants to grow. When cut hair is mixed into soil, the hair breaks down, slowly letting out nitrogen so it can help flowers and vegetables get big a little faster.
If you've got a wool sweater on, you're wearing a sheep's haircut. Sheep grow fine curly(弯曲的) fur called wool. All those curls make air pockets that trap heat, keeping the sheep warm. Farmers shear the sheep in summer, so the sheep don't feel too hot. And we use the hair to make warm clothes, socks, and hats. Wool can even take in rain without feeling wet. Wool also doesn't catch fire easily.
What does your hair say about you? Even many years after it has been cut, hair can tell surprising secrets. Because hair is made from bits of old cells, it has trace(微量) of chemicals(化学物质) that were in the body when the hair grew. When people are kept in the situation of dangerous chemicals, these traces remain in the hair, even long after they have disappeared from the body itself. Testing hair can help doctors know if there are dangerous chemicals in the food and water. Hair can tell another important secret—whose hair is it? This can be used to help solve crimes.
Hair does so many things for us. It keeps us warm and cool, helps farmers, shows mysteries, and provides endless styling fun. One thing is for sure—it's not just for wigs any more.
