Aging
Clinical observations and epidemiologic studies have shown that physical activity and, calorie restriction slow the aging process, whereas stresses, perhaps acting via increased production of glucocorticoids, accelerate aging.

Non-proliferative cells
Some tissues (called permanent tissues) consist of terminally differentiated non-proliferative cells, such as the majority of neurons and cardiac muscle cells. Injury to these tissues is irreversible and results in a scar, because the cells cannot regenerate. Skeletal muscle cells are usually considered nondividing, but satellite cells attached to the endomysial sheath provide some regenerative capacity for muscle.
