Living in a space

Scientists have been experimenting with the idea Living In Space for a long time . But it is not easy to live in Space. There is no gravity and the body needs a lot of adjusting to do. One of the scientists reported that his heart beat had become slower , and bones and muscles had felt weaker as calcium had been decreasing from them . His head had felt heavy as there was no gravity to keep blood down in the legs and there was also a feeling of Space sickness which is like travel sickness . Doing everyday jobs also becomes difficult . Water cannot be poured because it stays ion one place like a big ball. .If you want a drink , you must do it with straw from a closed container . If you sprinkle salt , it spreads all around you and heavy objects can be moved with one finger as they have no weight . Astronauts , therefore , need months of training to be able to adjust to conditions in Space.
