What causes human aging

　　1. Chronic inflammation As we age, the body’s organs become more and more inflamed, such as arthritis. It's not just the joints that are affected, but also brain cells, artery walls, heart valves... Infarctions and strokes are also related to inflammation.

　　2. Gene mutations. Many natural and man-made factors can cause genetic mutations. As we age, the cell "processing" mechanism becomes more and more irregular, causing malignant degeneration and deterioration of genes.

　　3. Cell energy depletion: Cell’s “power station””
