"Bernard can't deal with the pell-mell pace of London..." Pell-mell means in a confused or disorderly manner. There are two theories about the origin of the phrase. One is that it came form the Old French pesle mesle, a jingling rhyme, mesle meaning 'to mix'. The other theory is from the Italian palla 'ball' and maglio 'mallet', making pall mall, the ball game once played in the London street which became named Pall Mall
The word KARATE means 'empty hand'
