In fact there is a "Winery" a few miles from where I live now that in

available for tasting and there is no double that the more costly
wines do have a better taste then the low end bottles.
And without the added chemicals to make it taste like wine you get no hangover.
And what chemicals would that be?

Which doesn't support your claim. You wrote "Stradivarius can't be told from modern ones in blind hearing tests", The article states:
"the 82 listeners in the test reported that the new violins projected better"
"asked subjects which of the two violins in a pairing they preferred. Listeners chose the new violins over the old"
Yes, they could tell the difference.
This question has been studied many, many times, for decades. The
consistent results are that players or audience can't tell the difference.

more horseshit. Someone with training and experience can certainly
tell the difference in the flavor profiles, especially if you tried
to dupe them with a Gallo.
Which again doesn't support the claim that people couldn't tell the difference. It also doesn't state what qualifications the tasters had,
if any. I've had crappy $100 bottles of wine and excellent $25 bottles
of wine. Flavor preference is not the same than as "can't tell the difference".
If "telling the difference" is the same as "succumbing to the placebo effect," you've got a point. Otherwise, no.

I got a snake bite puncture on one of my TPU innertubes. I
haven't bought one of the commercial patch kits, so I
thought I would try a blob of Aquaseal. Known for it's
usefulness in repairing neoprene stuff and more, I thought I
would give it a go.
I tried to rough up the TPU innertube surface, but the
sandpaper didn't seem to have much if any effect. I cleaned
it with a little Windex, and after that had dried and I had
rubbed it some more with clean tissue paper, I applied a
drop of Aquaseal to each hole.
I have the stuff that takes about a day to solidify. I left
the tube undisturbed for at least 12 hours, though I can't
recall exactly how long, before putting it back in the wheel
and inflating.
This is on my gravel bike, with 40mm tyres that I inflate to
40-45psi.
The repair has held for a few hundred kilometers at least,
and now I have put different tyres on the bike, so I
inspected the repairs.
The blobs of glue seem to have spread and flattened a bit,
but otherwise have appeared to bond well and not leaked.
Good choice. I knew nothing about the subject before
snooping around just now. It seems Aquaseal active
ingredient is methylenediphenyl diisocyanate which is
compatible to TPU polyurethane.

Making a reliable bond unlike a simple contact adhesive such
as a stick-on patch.
Yup interesting stuff, I?d not persisted with TPU tubes, as on the Gravel bike tubeless has solved that, and TPU seem to puncture just as easily as butyl
I?ve toyed with idea of the MTB as with that and it?s burly tires punctures aren?t a thing, but on the other hand would one notice the difference with
a TPU tube in terms of feel?
Hence I?ve chosen to not fix what isn?t broke for time being.
