On the forum Mathcad MM for the input and work in discussions, it is necessary not only to enter a password, but ... blow into a tube for the test presence of alcohol. Same tubes are built into MM-computers, such as a webcam at normal computers!
This is done in some cars: a driver is drunk - the engine does not work.
I'm like, I try not to sit drunk, not only behind the wheel, but for working with my computer: done somethink in the forums or in the replies to the letters, and then (tomorrow) 
I've recently seen several of your propositions ...
I'll look for them.
Best regards,
Liv.
ENJOY REASONABLY !
