Although the secrets of a long life remain a mystery, there are now over 300,000 centenarians across the globe and the numbers are rising. Most of us will not survive to 100 no matter how many green vegetables we eat, but there is no doubt life expectancy is increasing. In Japan, 2.5 times more adult than baby diapers are sold. Australian life expectancy from birth is among the highest in the world with the average man living to 80.7 and 84.9 for a woman. It assumes no improvement in healthcare which can increase life expectancy further.
