Life expectancy has increased tremendously in the last few decades. Scientists at 23andMe would like to better understand healthy aging.  We want to understand how genetics and lifestyle affect how our bodies change as we get older.

Normal Aging

Normal aging results in changes in the cardiovascular system. It impacts bone health, the digestive tract, and many other of the body’s systems. Aging also increases the risk of developing a number of neurodegenerative disorders. Some of those include Alzheimer’s disease and Parkinson’s disease.
