Yeah, I was born in 1965. I have far more in common "experience" and "impact" wise with my sibling born in 1962 than my sibling born in 1968 - even though the latter is in the same "generation" and the older one isn't. I also found that who I hung out with in school had more to do with their parents' age than their own age. Some of my age were born to baby boomers and others the prior generation. I tended to have more in common with those born of the older generation like me, even if they were a year or two older or younger. The ones born to baby boomers tended to have different interests and behaviors.
