When we asked students what they want to be, they often talk about unusual jobs, things like teachers and doctors. But if you think about it, many people don’t plan to do their jobs. They just start doing them by accident. We have talked to two people with unusual jobs.

Emily is a dentist but she doesn’t work with people. She works with horses. After university she took care of animal’s health for several years, but she notices that there were few people who could help horses’ teeth. She decides to go to college and study again. Then she had to buy special tools, but she is never out of work. She’d always very busy taking care of horses’ teeth. “I couldn’t be a dentist for people now,” Emily said, “because I really enjoy working with horses.”

As soon as David could read, he read books about robots, but the robots he build today don’t look like the strange robot people in his books. He builds robots for industry. Early one he made up his mind to study math, science and computers so that he could break into the world of robot engineering. “Some of the math is very difficult.” says David, “but you must study math to be an engineer.” Fortunately he got top marks in all his math exams.
