"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.

"If your habits resemble those of average Americans, you generate about 4.6 pounds of solid trash per day. This adds up to big trouble for the environment. Americans are generating waste products faster than nature can break them down and using up resources faster than they can be replaced. How can we find ways to meet our current economic and social needs without compromising the ability of our children, and our children's children, to do the same? Our success will depend on understanding the difference between * Sustainable practices: practices that provide ongoing economic and social benefits without degrading the environment. * Unsustainable practices: "quick fixes" that fill an immediate need for resources. Over time, however, these practices deplete or damage natural resources so they cannot be used or enjoyed by future generations. In this exhibit, you can find out how to improve next year's environmental record. You'll learn how waste is handled now and how some communities are doing it better. In the activities, you can test your knowledge about hazardous waste we generate in our homes and try to shrink a landfill. "
