Maybe I remember the number wrong because (drum roll) I'm over 30 :-)
I don't think we're getting dumber, though. Yes, some function is
reduced, but I don't think enough to compensate for more experience and
better judgment. YMMV, but...
I'm assuming not too much chemical behavior, of course :-)

BTW, the above is an example of how good a typist I am, and why I try
to spell-check every posting. I obviously let that one slip through...

The problem: I don't really know what "it's all relative" means, except
perhaps that you're free to make your own moral or esthetic judgments,
or that it depends on your culture, or something. This has nothing to
do with physics, and vice versa. Except metaphorically, of course (as
if that helps me understand the phrase!).
As I understand it (and I'm not an expert), Einstein's theory says, in
general, that the laws of physics do not depend on where you are or how
you're moving, which could mean that "it's NOT all relative". However,
the theory also means that the numbers your get from a specific
measurement DO depend on where you are and how you're moving.
Metaphorically, you could say that the *measurements* sort of fudge
themselves to make the *laws* constant.
In short, it's not too simple :-)

OTOH, when I set my cell phone's ring, it is very loud, but when
someone calls me I never hear it. Einstein again?
