Like
it or not, physics plays a major role in defining what you might look
like. Here on Earth, two physical forces—gravity and time—are
responsible for one of the most obvious effects of aging: droopy,
sagging skin.
For
many men and women, this loosening of the skin is a major cause for
concern. Seen as a reduction of their physical beauty, this sign of
aging can cause some people to feel less confident about themselves
and frustrated at their helplessness against the ravages of time.
