The cells in the middle of your eye lenses have the highest life expectancy. They are present from birth and remain throughout your life, meaning they can live for decades.
-
Eye lens cells are unique because they are not replaced as you age. This means they don't divide like other cells, which allows them to survive longer.
-
While other cells in the body, like brain cells, can also live for a long time, they are not as long-lived as lens cells. Brain cells can live for over 200 years, but they are not as resilient as lens cells.
-
Heart muscle cells have a lifespan of about 40 years. This means they can live for a significant portion of your life, but they are not as long-lived as lens cells.
-
Hematopoietic stem cells are responsible for producing new blood cells. They have a lifespan of about 5 years.
-
Intestinal cells (excluding lining) are constantly being replaced. Their lifespan is about 15.9 years.
-
Skeletal muscle cells also have a relatively long lifespan of about 15.1 years.
-
Fat cells have a lifespan of about 8 years.
While lens cells have the highest life expectancy, it is important to note that all cells in the body have a finite lifespan. The lifespan of a cell depends on its type and its function.
