Our goal is to “die healthy”  Joe Chang
To extend your healthspan and stay youthful and vibrant as you age, you must affect aging processes where genes operate, at the cellular level. Dr. Joe Chang discusses the application of gene expression research to changing aging.

Gerontology scientist,  S. Jay Olshansky contended that  ‘Once you avoid the things that accelerate aging like smoking, obesity, excessive alcohol consumption, and excessive sun exposure, you’ve done about as much as you can to influence your aging process.’ 
We now know that this is not so. Dr. Chang, author of The Aging Myth, explains the key biological roles that epigenetics plays to construct the person we become and influences our aging.
We discuss how the different rates, time and intensity of aging phenomena in different tissues may be influenced by external factors, such as the impact of smoking on the lungs. The efficiency of mitochondrial energy production versus free radical release is altered with age as is the efficiency of autophagy, (cellular cleansing). These processes can be enhanced through epigenetic supplements. We  discuss the importance of supplying optimal prebiotics to the gut microbiome.
