As a person ages,   45   of brain cells and muscle cells decreases.   46   body cells die and are replaced by new cells. In an aging person the   47  cells may not be as workable or as capable   48   growth as those of a young person.

    Another   49   in aging may be changes within the cells   50   . Some of the protein chemicals in cells are known   51   with age and become less elastic (有弹性的).
