Take a step back; can you imagine musicians at the age of 50 still remixing? Seems highly unlikely to me, sure there’ll always be some of us who will, but how many?
Basically, all this we see around us will vanish in time. Could I be wrong?
Hmmm... goodness Neil, that does sound depressing.

Whilst I have to agree on a certain level with our view, and indeed with Thomas' too, matching the 32/33 age group you mention, I have to say: Take it easy guys. It's nothin to worry about really. These feelings come and go, and to be totally honest, I've had them even at the age of 18. I recall sitting around with my best friend, playing games on the 64 or Amiga and wondering how long this will last. Honestly.
And then, with 21 or so, I had an A1200 with HD (whooo!) and had tons of games and played: Nothing. And I remember thinking: `I knew it! What a shame...´ Instead, I played with my girl, did `serious´ stuff and started working/studying et al. Then, at 25 or so, I got back into gaming like a madman, collecting consoles, games and magazines. No idea where it came from, but it was like a rebirth. And it rejuvenated my life. Then, at around 28, I again focussed on my work, my `grown-up´ life and family & friends. Today, I'm moving house, hosting international meetings while at the same time, I remix ST music for a CD, write a book on video games and play Resident Evil 4 to the brink of dawn (nice hidden pun eh?).
To cut a long story short: I don't miss anything. Sure, the interest in remixing, the `good 'ol days´ and playing games wanes every now and again - but it sure as hell returns. I'm perfectly happy to go through these phases - being `grown up´ and a `big kid´ at the same time. I'm just grateful to have these interests to accompany me throghout my life - many of my friends or relatives only have their work and the couch. Aren't we glad we don't?
That said, happy remixing, playing, working and errr.. just living!
