We have written repeatedly on our blog about the importance of proper nutrition, social interaction and exercise is key to keeping the mind and body healthy for seniors. A new study from Arizona State University Edison College of Nursing and Health Innovation had participants either ride a stationary bike or do stretching exercise for six months. Those who took part in the regular exercise program had significantly less memory loss than those who don’t follow a particular exercise regimen. The results were published in the Journal of Alzheimer’s disease.
