LAS VEGAS (Reuters) - Republican U.S. presidential candidate Mitt Romney is physically fit with no serious ongoing conditions and appears younger than his age, according to a letter from Romneys doctor released by the campaign on Friday.
"He is a vigorous man who takes excellent care of his personal physical health," said Randall Gaz, a physician at Massachusetts General Hospital in Boston.
"There are no physical impairments that should interfere with his rigorous and demanding political career."
The Republican takes low-dose aspirin and 10 mg of the anti-cholesterol drug Lipitor each day, but no other medications on a regular basis. He has a resting heart rate of 40 beats per minute, Gaz said.
An adults normal resting heart rate ranges from 60 to 100 beats a minute, according to the Mayo Clinic. But for an athlete, the rate may be closer to 40 beats a minute.
"A lower heart rate at rest generally implies more efficient heart function and better cardiovascular fitness," the clinic says on its website.
Romneys campaign released details of the health of Romney, 64, and his running mate, Wisconsin Representative Paul Ryan, 42.
Brian Monahan, the attending physician for the U.S. Congress, termed Ryans health excellent and praised his patients "important preventative lifestyle choices" including vigorous exercise and a healthy diet.
