Maybe it's that any fresh experience has an excitement of its own. Hey, an old pair of shoes has a comfort of their own that new can't match. So there's things about new that "redux" can't match, and there's something about patina that can't be faked.

BUT

What I'd rather suggest:

Try the old LPs and the Squirt again. Try 'em on a different day or at a different time of day. Try the Squirt again when you're really thirsty (having worked up a sweat out in the yard -- or, for Big Mick, after flirting with a colleen). Try the old LP late in the evening when the lights are low and the room is so quite you can hear the shadows move.

...then come back and tell me if those old things aren't as great as ever.

If I had tried Squirt, or heard those LPs for the first time under different circumstances, they might not have impressed me in the first place (to have remembered them this long and this fondly). Assume the same of the times and moods of the present.
