Living longer puts more pressure on pension funds to seek higher returns, to downsize corporate fat, to internationalize the search for high quality investments and less risk.

China has an army of 3.2 million, the world's largest, and maybe the world's fastest growing military budget. Population growth is creating a number of new world powers. Nigeria's will more than double to 274 million from 109 million Bangladesh will double to 200 million from 104 million Population change can lead to war or famine Some countries, however, with growing populations want to reverse history.
