Regular exercise appears to decrease the risk of developing primary breast cancer by 20-40%; but for post-menopausal women, the numbers change to 20-80% reduction in risk. Additionally, for each additional hour per week of exercise, the risk of developing breast cancer decreased by 6%. (So encourage the women in your life who haven't had breast cancer to get moving!)For those of us who have already been diagnosed with breast cancer, physical activity before diagnosis appears to have little effect on breast cancer outcome. In examining the studies, the authors found that intermediate or high physical activity prior to breast cancer diagnosis did not affect breast cancer deaths, but did show some benefit for overall mortality.

On the flip side, it's clear that coffee isn't for everyone. Its legendary jolt in excess doses -- that is, more than whatever your individual body can tolerate -- can increase nervousness, hand trembling, and cause rapid heartbeat. Coffee may also raise cholesterol levels in some people and may contribute to artery clogging. But most recent large studies show no significant adverse effects on most healthy people, although pregnant women, heart patients, and those at risk for osteoporosis may still be advised to limit or avoid coffee.The bottom line: "People who already drink a lot of coffee don't have to feel 'guilty' as long as coffee does not affect their daily life," says Hu. "They may actually benefit from coffee habits in the long run."In other words, consume enough caffeine -- whether it's from coffee or another source -- and you will likely run faster, last longer and be stronger. What's enough? As little as one cup can offer some benefit, but the real impact comes from at least two mugs, says Graham. By comparison, it'd take at least eight glasses of cola to get the same effect, which isn't exactly conducive for running a marathon.
