Ageing is associated with a decline in body functions, an accompanying change in structure, loss of lean mass and a relative increase in fat mass over time. This article looked into the physiology and physical changes associated with human ageing through journal and book review. Research over the past several decades has progressively reduced the number of these changes considered to be intrinsically due to ageing while it has increased those that are attributed to age-related disuse, inactivity and degenerative disease. Since these changes are typically associated with ageing, they tend to be seen as negative in our society. However, it may be noted that smooth, un-wrinkled, clear skin could be negatively valued since it may indicate inexperience, unfamiliarity with life's pain and pleasures, and irresponsibility. It is therefore fascinating to study and old face and try to imagine what history might be written in those wrinkles and folds that are so unique to that face.
