July 10 (UPI) -- They say age is all in your mind -- and that might literally be true, a new study reveals.
People with "young" brains -- brains aging more slowly than their actual age -- are much less likely to die or develop Alzheimer's disease than those with "old" brains suffering from accelerated aging, researchers reported Wednesday in the journal Nature Medicine.
Results show that having an extremely aged brain nearly triples a person's risk of dying during a roughly 15-year period.
At the same time, people with extremely youthful brains had a 40% lower risk of early death, researchers found.
