Some Body 'Clocks' Age Faster Than Others

Tue Jul 23, 2002

By Merritt McKinney

NEW YORK (Reuters Health) - The aging process can take a toll on the body's internal rhythms, and now new research suggests that some body parts age faster than others--at least when it comes to telling time.

In a study of old and young rats, internal "clocks" in certain tissues became less reliable with age, but others "kept time" as well as they did in younger animals.

That's true, up to a point. As a general rule, the American Heart Association says any reading below 120/80 is good. Except if your pressure gets too low. That can lead to feeling lightheaded, fainting and even heart attack.

If you do have extremely low blood pressure, your physician should investigate the reason. Common causes for the problem are certain medications, illnesses or shock.

Brain Scans Show Why We Love Cooperating

By Alison McCook

NEW YORK (Reuters Health) - New research reveals why people often cooperate with each other, even when it is not necessarily to their advantage to do so.

A group of researchers based at Emory University in Atlanta, Georgia, found that when a woman is involved in a situation where she is cooperating with someone else, she experiences activation in brain areas that are also activated by "rewards" such as food, money and drugs.
