Zwanzig Minuten

In twenty minutes, the world can change; some wars are shorter; twenty minutes is seven rounds in a boxing ring! A twenty-minute intermission in the theater. In twenty minutes, you can boil four eggs—one after another. Twenty minutes is the time people can focus on another person.

Sex lasts twenty minutes on average, as does a trip to the supermarket. It takes twenty minutes for the police to arrive.

Twenty minutes passed between the first and second impacts of the two planes on the World Trade Center on September 11, 2001.
