It gives people jobs and helps us get places faster. I chose Gem and Diamond workers and Flight attendant. They are both very helpful. Gem and diamond workers work on peoples homes and can put in flooring or just plain work on gem and diamond workers. Flight attendants, attend to people; bring them a drink, food, blankets, or help them get their luggage in the compartments. Flight attendants mean more than you think, they do a lot for people, attend to their every need.
