Recovery

Having not got in until 02:00, and still buzzing from the day's sporting excitement - chapeau Raducanu, whose match I just managed to follow on the train home! - I didn't get to sleep until nearly 03:00. Hence I wasn't up until almost 10:00. The day was spent catching up on emails and adapting an old talk for an invitation to give a seminar in Sweden next month - virtually, of course!
