Tucson- Exercise, not body fat, may predict how well people recover after a stroke.
A new Harvard study looked at the exercise habits of 1,300 adults three years before they had a stroke. People who worked out vigorously at least three days a week were more independent after their stroke, compared to those who were sedentary. And BMI was not a factor in predicting a patient's level of disability after a stroke.
Smoking still leading killer
Smoking has decreased by nearly one-third worldwide since the early 90's but new data reveals it's still the leading cause of death and disability in 100 countries.
Researchers report that more than one in ten deaths are caused by smoking and half of those occur in just four countries, the U.S., Russia, China and India.
And although the percentage of people who smoke is down, population growth has led to an increase in the overall number of smokers.
