LIVING IN SPACE
Human bodies are amazing. Oour eyes adjust to light and dark. Our hearts speed and slow as needed. Our skin sweats to cool us or makes goose bumps to keep us warm. We shouldn´t be surprised that our bodies also adjust to a lack of gravity and life in insolation. Some of the changes are unpleasant, ohters amusing. The spce station offers a wonderful opportunity to study these changues and to test ways to stay healthy on long trips.
