"I'm getting old"

i guess im gonna have to get used to it, folks even in their 30s (20s?) saying they feel old etc. maybe because so many of them say, repeatedly:

• "music/comedy/tv etc these days is crap",
• "im gettin old" when they have the slightest ache,
• "it's too hot/cold etc out",
• "when i was a kid movies/bread/candy etc cost a dollar/50 cents/ negative 50 cents" whateva,
• "when i was a kid we didn't have mobile phones" etc. so "you kids have it easy".

did these geniuses ever think that since old farts have been using these platitudes for one billion years, maybe THAT'S why they';re getting so friggin old? which doesn't make sense, you can beat 'em, why join 'em?
