Exactly. That's what makes the entire term even more ridiculous.
I think that's why they changed it a long time ago, to make older people feel special.
Besides, lots of people are born in 10 year time periods. Plenty for an entire generation.
After all, do we really even need to emphasize generations, anyway?
We're all just people and the same stuff is out there for us to discover.
I'm considered "old" because I'm not into most stuff from the last 30 years.
Yet, I was born within the timeframe within either definition.
Just a pet peeve of mine, mostly.
I think this is the part where I just relent and say "Semantics" before closing the subject.
