Do you feel like age is catching up with you? Have you noticed wrinkles, hair loss, reduced physical energy, or diminished sex drive? Do you get sick more often than you used to?
Although we typically think of the external signs of aging, with the emergence of wrinkles and graying hair, aging is also an internal process that has roots at the cellular level. All the organs of our bodies are made up of individual cells that have limited life spans. While we are young, our cells divide many times as we grow. Our cells are capable of repairing themselves, communicating with other cells , and interacting with all the physiological molecules that ultimately define our current state of health. Scientists have discovered, however, that our cells have a limited capacity to divide and repair.
