"Use Discovery Health's free target heart rate calculator to find out what your target heart rate is. Simply put in your gender, intensity level and age, and let Discovery Health's free target heart rate calculator work for you.
Your Target Heart Rate, from 60 to 80 percent of the maximum your heart can beat, should be your goal three to five times a week for 20 to 60 minutes (excluding warm-ups) to maximize the health benefits of cardiovascular activity, including losing weight. People who exercise regularly do build up endurance, but they gain little additional value when their heart rate goes above 80 percent of their maximum.

"Teenangels are a group of thirteen to eighteen year old volunteers that have been specially trained in all aspects of online safety, privacy and security. After completion of the required training, the Teenangels run unique programs in schools to spread the word about responsible and safe surfing to other teens and younger kids, parents, and teachers.
They write columns for Web sites and become expert public speakers and researchers. They work with companies like Disney, Microsoft and AOL and are trained by law enforcement agencies; their tuition includes experience in making presentations to groups of students in schools and/or at community events.
Teenangels have even been to the House of Representatives in Washington D.C., for the WiredKids Summit, where they presented their research to a powerful and influential audience.
At the urging of our Teenangel volunteers, a special group of volunteers will be able to continue as Teenangels after they become eighteen years old and a new group of Tweenangels has been formed for those between seven and twelve years of age. "

"Quizlet is how I occupy my free time and even some of my non-free time.
My mission for Quizlet is to make learning vocabulary not a chore. I know a lot of teachers assign vocabulary to students, but few students actually "absorb" words into their vocabularies after they take their test. Which kind of defeats the purpose, right? So Quizlet is my response - it aims to make learning fun, thus make learning effective. At the very least, it can help students do better on quizzes and tests even if they don't fully "absorb" their words."
