The numbers of our boomer lives. So you launch your market messages with an assertion about the addressable market for a product. So one of the timeworn ways used is to start with a concept. For example, they are going to turn 65 and are retiring -- or perhaps they are unretiring and starting businesses -- at a rate that is big, really, really, big. So let's consider the following oddity. In 2010, boomers were going to turn 65 at the rate of 10,000 per day for the next 18 years. Then in 2014, you perhaps noticed a different phrase about boomers, including this one from AARP: They are going to turn 65 at the rate of 8,000 per day for the next 18 years. This caused me to wonder, what happened to 2000 of them? Could they have died? Left the country? How many people there are in a certain age range making up an addressable market -- that should be fact, right? Sort of. I turned to Brent Green, an advisor to boomer marketers.
