The Census Bureau in America says that there are now nearly 2 million people in the USA in their 90s.

(This is three times as many as there were back in 1980 and the number is projected to reach 9 million by 2050, but aging isn’t just a phenomena in the West, it is a global issue:  Worldwide, by 2050, the increase in population ages 65 and over is forecast to be 2.5 times that of the population ages 0-4. This is an exact reversal of the situation in 1950.  Of course some people think this is a problem, but when it comes to aging, I for one am all for it!)
