    How old is the oldest cell in your body?

    If my memory serves me well, the cellular structure of the body is in continuous flux and  renews itself over 7 years.  On the other hand, I may be thinking of something else, I'm knocking on a bit now.

    It depends on what cell it is. e.g. blood cell, skin cell, stomach tissue cell

    Recent studies have shown that few cells live as long as the individual they belong to without renewal. A majority, if not all, the cells making up the cerebral cortex belong to this small group. The life span of some other human cells are as follows:

    Lifespan of select human cells:

    Cell Type -- Lifespan

        * Granulocytes -- 10 hours to 3 days
        * Stomach lining cells -- 2 days
        * Sperm cells -- 2-3 days
        * Stomach lining cells -- 2 days
        * Colon cells -- 3-4 days
        * Epithelia of small intestine -- 1 week or less
        * Platelets -- 10 days
        * Skin epidermal cells -- 2 - 4 weeks
        * Lymphocytes -- 2 months - a year
        * Red blood cells -- 4 months
        * Stomach lining cells -- 2 days
        * Macrophages -- months - years
        * Endothelial cells -- months - years
        * Pancreas cells -- 1 year or more
        * Bone Cells -- 25 - 30 years

    Brain cells must be old,because i read somewhere that they don't die.So it will be as old as you.
