Did you notice the world is fast aging?

Population aging is a global phenomenon affecting every man, woman and child and has a profound implication on many facets of the human lives. The 21st century will witness even more rapid aging due to the baby boomers after World War II. Aging is enduring, we cannot and will not return to the young populations that our ancestors knew. Although the concept of old age differs in different countries and cultures, gerontology remains the greatest challenge in this era. As lives develop, aging is continually evolving. Before a person is born the aging process has started. Once we start to show impairment of our organs, cognition, hearing,vision and our skin become dry, inelastic and pigmentation appears, wrinkling and sagging and hair become thin or vanishing, do we really want to live to a ripe old age?
