My mother moved in with us at the age of 70. At that time, she was taking one medication for her high blood pressure and managing her diabetes with diet. Otherwise, she was in good health, quite active, and loved to travel. In the 11 years since, she had a heart attack, a triple bypass, a stent in her heart, bypass and a stent for an abdominal aneurysm and a bypass into the legs to improve circulation. She's now on two medications for her heart, one for diabetes, two for her pressure, and one for her cholesterol. She's also suffered a hearing loss and has trouble walking long distances without a walker. In other words, she got OLD. I would hate to think that she had these health problems while trying to run the country. It's absurd to think that she would be up to the stress and long hours necessary.
