Fun Fact
The Pomodoro Technique, developed by Francesco Cirillo in the late 1980s, uses 25-minute focused work intervals separated by short breaks. The method is named after a tomato-shaped kitchen timer Cirillo used as a university student ('pomodoro' means tomato in Italian). The technique leverages the psychology of time-boxing: knowing you have a defined period helps maintain focus. After 25 minutes, a 5-minute break allows mental recovery.
