Programs should create and enforce written policies on the designation, retention, and disposal of abandoned embryos. In the absence of program–specific policies, it is ethically acceptable for a program or facility to consider embryos to have been abandoned if at least 5 years have passed since contact with an individual or couple, diligent efforts have been made to contact the individual or couple, and no written instructions from the couple exist concerning disposition. In such cases, programs may dispose of the embryos by removal from storage and thawing without transfer, though in no case should embryos deemed abandoned be donated to other couples or be used in research.

Want to cut the length of your workout while maintaining or even increasing the benefits? Try interval training, a type of cardiovascular workout in which you alternate bursts of peppier exercise with slower–paced recovery periods. Intervals make you work more efficiently: Your overall intensity is greater, so the length of your workout can be cut by about 20 percent. Plus, a growing body of evidence suggests that this approach yields health benefits comparable or superior to traditional exercise. Interval training has been linked to improved levels of HDL (good) cholesterol.
