Speed Reading — Nose Shape - Level 2 — 100 wpm 

This is the text (if you need help).

Why is everyone's nose a different shape? Researchers have a possible answer to this. A recent study says the Earth's climate could change the shape of our nose. The study found that people with wider noses live in warm, humid areas. People with narrower noses live in colder, drier places. The nose makes sure that the air we breathe is warm and moist when it gets to our lungs. The nose is a little like a temperature controller.

Researchers used images to measure the nose width and height, and the distance between the two nostrils of over 2,600 Africans, Asians and Europeans. The study could help people with the heat or cold, and the humidity if they go to other countries. It could also help with breathing problems. A researcher said it is difficult to predict the future shape of the nose. This is because we travel a lot, our lifestyles have changed, and because of climate change.
