Regular exercise not only helps your heart - but your eyes too.  And another study questions the benefit of mammograms when it comes to saving lives. 

A new 25 year Canadian study finds annual mammography screening in women ages 40 to 59 does not cut breast cancer deaths.  Researchers suggest mammograms are not any better than physical examinations or usual care.  The American College of Radiology calls the research "a misleading analysis based on the deeply flawed and widely discredited Canadian National Breast Screening Study."
The pain reliever found in Aleve and many other medications may not be safer on your heart.  An FDA advisory panel says naproxen does not appear to lower the risk of heart attack and stroke compared to other anti-inflammatory medications like ibuprofen.  Federal Health Experts say recent studies about its potential benefits are inconclusive and do not warrant label changes.

And everyone knows exercise is good for you.  Now scientists at the Atlanta V-A Center say it may also help your eyesight.  They found that regular exercise can preserve damaged nerve cells in the retina.  The study was done on mice but researchers hope it could one day lead to new treatments for blindness.
