as 'Roger Rabbit' would say... 'Pppppppppllllleeeeeaaaasssseeee'... :-)
our nervous systems, innately, incorporate =vast= capacities to reconfigure
their internal 'states', including their internal biochemistry. i'll give a
little example from my own experience.
when i was younger, it was sometimes the case that i'd get totally
'schnokkered' on no more than 2 12oz beers.
i gave up drinking, almost completely, in 1986. but a while back, at a
dinner with a well-loved friend, i had some wine... i didn't get
'schnokkered', but i did 'feel' the effects.
the other night, wishing to 'lighten-up' a bit, i purchased a couple of 24oz
bottles of beer, drank 'em down... =nothing=... it was as if i'd drunk
water.
[i did note a days-long 'after-effect, which i also recall from earlier days
[and which is the main reason i'd decided to abstain from alcohol], but it
was 'just' a neural 'lethargy'.]
the point is that, depending on the momentary environmental conditions [the
presence of a well-loved friend at a pleasant diner, vs. the exclusive
pressence of my need to accomplish the communication of the Science i've
done] my nervous system can alter it's biochemistry to the degree that
alcohol no longer has a 'releasing' effect.
it's no 'big deal'... just the outcome of having done physically-real work
that directs the ongoing development of structure internal to my nervous
system.
my jaw hung down the other night when i realized it was so... our nervous
systems are much-more than folks've realized.
