As a person ages, 30 of brain cells and muscle cells decreases. 31 body cells die and are replaced by new cells. In an aging person the 32 cells may not be as workable or as capable 33 growth as those of a young person.
Another 34 in aging may be changes within the cells 35 . Some of the protein chemicals in cells are known 36 with age and become less elastic (有弹性的). This is why the skin of old people wrinkles (皱纹) and 37 . This is also the reason why old people 38 in height. There may be other more important chemical changes in the cells. Some complex cell chemicals, such as DNA and RNA, store and 39 information that the cells need． Aging may affect this 40 and change the information-carrying molecules so that they do not transmit the information as well.
