he's talking about teenagers that grew up in each decade. teenagers in 2000 are different than teenagers growing up in 2010
This is when I know it's time for bed. Thanks

Says the person who isn't elderly, I suppose? "They all look alike" usually means "I don't look too closely." 
You mean elderly people are chinese? 
Prepare for the hate tweets 

Should i wrap my cuffs up or take off the shirt??
You stop giving a shit after forty.
You're not even a teenager for 1 decade,let alone change over several. #Pishfacts
Not actually really true.
I have blue chunks/highlights in my hair and I plan to keep them there even when I grow old:) Oh yeah, and I will still wear my Calvins.
Mainly bc of cosmetics, better health & longer lives. IMHO, aside from clothes changing, teens are the only group that still looks their age
My boss is 78 and he looks like what people used to look like at 65. People look a LOT younger now than they did a few decades ago.
Not true. My parents are in their 60s and they look and dress young. Just a decade or two ago 60 was like an OLD OLD person....
You're a teenager. How would you know?
He's 29.
Not to mention corpses.
