Just two more hours of sitting at your desk at work or kicking back in front of the T.V. may be linked to a higher risk of several types of cancer.
That's according to a study published this week in the journal of the National Cancer Institute.
Researchers looked at more than 40 previous cancer studies that point to a link between sedentary behavior and increased risks of colon, lung, and endometrial cancer.
A new study in the journal Pediatrics shows boys who have hit puberty have a greater response to caffeine compared to girls.
Researchers found no difference in how caffeine affected eight-to-nine year-old boys and girls.
But boys between 15 and 17 reacted faster to caffeine than girls of the same age.
The American Academy of Pediatrics recommends children have no caffeine at all.
Young women who suffer from depression are twice as likely to suffer a heart attack or die of heart disease.
A study in the journal of the American Health Association looked at more than 3,200 patients, and found that women age 55 or younger and who had moderate to severe depression had double the chance of experiencing a heart attack in the following years.
That is about the same risk as smoking or having diabetes.
