The guy is an idiot, the boomer generation is those people born from 1946 to 1964.
All these "generations" are inventions of the human mind. There is no "correct" definition but some definitions make far more sense than others.
When you think about it, a "generation" should group together individuals with a similar experience based upon their era of birth.
A time span lasting from 1946 to 1964 is far too long for a single "generation". For example:
The year is 1967. What does 21 year old John, a combat infantryman in Vietnam, have in common with 3 year old Timmy, two years out of toilet traning?
In 2010, how will John and Timmy remember "The Sixties"?
Sometimes, the generation born between 1954 and 1965 is referred to as Generation Jones
