my instructor told about something he read or heard:

one buddy would show so many fingers and the other buddy would responed by
showing the numbers of fingers shown to him plus one ie. first buddy shows
two fingers the second buddy shows three finger as a test for narcosis

personally, i haven't had a chance to try it ... cause i wear mitts and not
gloves (showing fingers is kinda difficult) ....  but my understanding is
that narcosis has an element of task-loading stress  ...  so, i question how
accurate any given test is, if the only stress is performing this test (and 
not finding the anchor and not checking your gauges and not sending up an
emergency ascent line in dark murky water with a one knot current) .... are you
_really_ determining your level of narcosis, with a simple test or mind game?

peace
