The job of a scientist is to find out the truth in the field of science. It is  challenging profession. Scientists usually have to do thousands of experiments in order       prove something. Although they are often disappointed     they fail, most of them never give up. My next door neighbour is a scientist. He studies radiation. He   always working in his lab, trying to figure out all the mysteries make him puzzled. When I met him the other day, he had just come back   work, looking excited. He told me he had had a breakthrough. He sounded so thrilled. Then I noticed that    was wearing shoes that did not match. He must have been working too hard to notice! I think it’s good to do a job that you are interested in. you will get bored easily.
