Shorter than that now as they target to "tween" between "childhood" and "teenager" and now that "childhood" bracket has been further subdivided as a demographic they advertise to.
Figure a "generation" now is 3-4 years.
Pretty amazing. My point is that, being born in 1961, I never remotely
identified or agreed with the "boomers". My family was conservative
and had utter distain for the whole group. By the time we hit high school
(late 70s) the hippy thing was long gone, Vietnam was over and Carter was
looking like a fool. I cast my first vote as a cadet at West Point for Ronaldus
Maximus. We were never "vexed" about much of anything. Just living life,
trying to do the right thing and succeed.
