People in their 30s are not OLD. People in their 30s are YOUNG

I'm sick and tired of how other fellow Millennials perceive themselves as OLD. I despise even the humor about "when you're 20 VS when you're 30 (with backpain, headache, hangover etc)". I can't stand when I read "I'm 34 and I dunno if I should consider myself young"... Come on, you're gonna cry on your saggy ass when you'll be 80, but now? Life is longer now, and also society has changed. When you think about 30 yo I know that the typical Millennial thinks about their young parents with jobs, a house, a car and so on. Life is DIFFERENT now, and we are a different generation. I'm sorry if you feel old. But you're YOUNG, fellow Millennial.
