SLFguy,
For a member of aircrew the limit is 20 mg/100 ml of blood.That works out at about 1/2 pint of average larger.For a driver it is 80mg/100ml of blood..2 pints appx of average strength beer.At those levels it might be hard to know where the borderline is....It takes many years of time and effort to get a driving seat in an airliner.
But you are missing the point here.
The increase in intrusive monitoring is the problem.Why now has it become a issue?.It unnerves me to see a blind acceptance of yet more draconian measures by the general public.At some point we have to draw the line.Unless you want to live in an Orwellian state.
