The cells in our body are continually replaced, especially those exposed to the harsher environments of the skin or intestine. Even cells in tissues that generally experience less turnover often regenerate after an injury. While scientists believe other cells in the human body, such as those in the brain, have longer life spans, they still don't know much about how often cell replacement occurs, if at all.
