A new report from the government finds those in the U.S. are living longer.
    
The National Center for Health Statistics revealed that men are now living, on average, to age 75 and women to 80.
    
The study also found the mortality rates for 15 leading causes of death are down-- including flu, heart disease, stroke, diabetes, hypertension and cancer.     
    
Doctors gave the credit to medical advances and patients.

"Clearly there's some things we're doing right!" said Dr. Len Lichtenfeld of the American Cancer Society. "We're smoking less, hopefully we're a little more active than we used to be and we're doing more things for our health."

"We're getting screened and we're becoming more engaged with what we need to do," he added.

The study found women are still living longer than men, but the gap has now narrowed to five years.
    
Still, doctors fear the increasing rate of obesity could erase all of these gains.
