The Rook told Number 6 that he takes too many risks after he'd broken the aerial off one of the taxis. To which Number 6 replied "Let me worry about that." The doctor-Number 22 read from a psychiatric report, the result of tests carried out on Number 6. That he has a total disregard for personal safety. Well there was no need to carry out tests on Number 6 in order to find that out. All the doctor had to do was to read Number 6's personal file, and of the episode when he had previously put to see aboard a sea-going raft, to find that out!
