Cells play a variety of important roles in our body. They provide the blueprint for everything we are and everything we become. They can store and release oxygen, create energy, communicate with each other to maintain our health, and store the food we eat, later distributing the nutrients in that food throughout our body.
Over time, cells fatigue and become damaged. Old cellular matter that accumulates begins to degrade cell functionality. This can lead to a variety of health problems and age-related illnesses. Thankfully, our bodies have an answer for the cellular renewal process. It's called autophagy.
