Ooooh. Lots! Let me count the ways:
1) I still dress like it's the early 90s
2) Anime and manga are just pretentious ways of saying cartoon and comic. Other cartoons and comics have been art for the best part of a century! Asterix is art and I don't describe it in French.
3) Also it's conformist and badly drawn!
*Shakes wizened fist*
4) I moan that Sousixie and the Banshees and Bauhaus were goths and it does not mean 'generic metal'! (I've been moaning about that since the 90s...)
5) I remember when there were more than ten video games that just get slightly different graphics and sold as something new for about twelve grand a pop or however much Generic Shooting People 394 costs.
6) I can't eat nothing but toasted white bread for two days and drink a bottle of vodka plus beers and still live, like in the good old days.
7) They all spell my name right on bills these days due to practice.
8) I can always remember worse weather.
9) I can always remember better weather.
10) I'm old enough to remember changing the nappy of somebody who is an adult now.
11) I sneer at people who laugh at the sound quality of walkmans while they listen to an MP3 on earbuds.
12) I consider the really truly great advance in modern phones is the off button. Now
that is progress!
14) I'm way more superstitious nowadays.
15) I am nostalgic for old adverts.
16) I have to mentally work out the actual value of things due to inflation leaving me behind...
17) I prefer large print. (I'm viewing this at 170%)
18) My parents are only 33% older than me.
19) There is only one Transformers movie. It had Orson Welles, Eric Idol and Leonard Nimoy in it and Weird Al Yankovich on the soundtrack.
20) Someone wrote a comedy version of A Christmas Carol with me in mind as Scrooge.
21) That was ten years ago.
22) I've had a conversation with someone younger than my t-shirt.
