She's 75-years young (you read that right), a vegetarian for the past 25 years and a former marathon runner. Today, she maintains a daily fitness program of yoga and cardio.
One day we trained next to one another on the elliptical. I asked her why she decided to become vegetarian. She said her father had died in his 40s of a heart attack. His death scared her enough to evaluate her dietary choices and overall lifestyle. Through research, she concluded that a diet rich in vegetables, whole grains, fruits, beans and legumes would make her more heart healthy. (It's worth noting that at 75 she doesn't take any medications at all.)
The whole notion that weight gain and pills are a normal part of the aging process is a fallacy. How we live in our later years is determined by our lifestyle and dietary choices today.
