Being young is often taken for granted in the early years, and this can refer to your state of mind as well as your physical fitness and chronological age. Youth usually means having more energy, being in better physical shape, and being passionate about your appearance. Being young is often a fond memory for the elderly, and tales of the fountain of youth show how much this attribute is prized. As we age we tend to slow down mentally and physically, and physical health tends to deteriorate more as time goes by.
