What are the biggest problems that society will have to deal with in the new age？There are diseases like AIDS and cancer．There's climate change，of course．And what about producing enough cheap food and energy for the world's growing population？Who's going to solve all these terrible problems？Yes，politicians and world leaders will have a big part to play．Yes，businesses will need to create the economic wealth to pay for some of these things．But who's going to make a much greater difference to something like AIDS or climate change？It's going to be a scientist．It is the scientist who can turn some new bit of science into a new technology to solve these problems．

If you like thinking about the world around you，why not become a scientist？It doesn't mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine!Scientists do all kinds of amazing things that are actually interesting!

Military scientists develop not only new weapons but new military technologies that could help make wars out of date． Forensic（法医的） scientists work with the police to find quite small clues to catch criminals．Scientists work in schools and colleges as the teachers and professors who will train tomorrow's scientists．Don't think a scientist is far away!Maybe you like cooking？You could be a food technologist helping to keep fruit and vegetables fresher for longer．Perhaps sport is your thing？Do you know that most top athletes work with sports scientists in order to improve their performance？You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world．

Looking for something to do for the rest of your life？My advice？Take a long and hard look at science．It is interesting and ever．
