Thank you for that.
Would I be out of line to suggest that what you're saying is that a person who has a high tolerance to alcohol, such as a person who may be an alcoholic, can appear to be functioning in everyday life like most people--they've learned how to walk a little bit straighter, they've learned how to cope with effects on such motor skills as writing or speaking--but then, when faced with an abrupt change in circumstance, they can revert to the same thing that you or I would given the same amount of alcohol?
