0-2 hours (2 hours in case of severe hangover).
In 2000 we had an Ostankino TV tower on fire, it burned severely, and we had no TV in Moscow for three days. The feeling was beautiful. Looked like the sun was brighter, people were more friendly, I woke up in the morning hearing the birds singing... As if the huge load of brainwashing was removed, you could literally feel it in the air.
