What does a respiratory therapist do? It's a good question and it is one that is answered in great detail on the National Institutes of Health's Office of Science Education "Life Works" homepage. The site was designed to help young people learn about different careers in the life and medical sciences. Visitors can browse for information on more than 100 careers by title, education required, interest area, or median salary. Each career profile contains an interview with a specialist in each field, and many of them also have video clips of the specialist at work. The site also has a career planning timeline that provides information on everything from preparing to pick a college to looking for financial aid. Finally, visitors can also look into finding an "e-mentor" that may be able to assist them wherever they might live.
