Human advancement has allowed people to live longer and healthier lives the world over—and the numbers say it all. 2006 recorded almost 500 million people over the age of 65 worldwide, and this number is expected to double by 2030 . This means that seniors will comprise one out of eight people on earth. In addition, developing countries will see a rapid jump in their senior population by 2030, with some estimates as high as 140% increase.
