No other trend will do more to reshape our cultural, political and economic landscape than the irreversible rate at which the world is aging. If this is the first time you've thought about it, you'll be awestruck by the facts. Globally, the number of people 65 and older is expected to double to 1.5 billion by 2050, and the number of people 85 and older will grow by 300% during the same time period. Here in the U.S., 50% of today's adult population is 50 and older, while in China, the number of people over the age of 60 is larger than the entire population of Russia. At these rates, it's not surprising that adults 65+ will soon outnumber children under five for the first time in world history. Think wheelchairs, not strollers. We live in the Age of Aging.
