You could change places with another person. I would like to choose a rock star singer to change for one day and I would like to change with him for some reasons. On the one hand, I love music. In fact, I studied four years ago to work as sound engineer. Also, I really like to see what it happens behind of public can see. I would do many concerts around the world and I am sure that I would enjoy so much. On the other hand, I would be able to use being a famous people to help different charitys. I would be an example for other celebrities. For example, with the concerts which I would do around the world, I would donate a percentage for poor people and when the tour finishes I would do an auction for my guitar and some instruments, and that money would be given to differents NGO. To sum up, if I would can to choose with one person for a day, I would choose a rock star singer because I believe that I would enjoy so much and I would can to help to poor people.
