NS, I hope that watching the tennis has been a bit of a distraction from your unwelcome medical news.
I turned on Five Live Fridayevening and listened to the fourth set of men's semifinal, then turned off. turned back on a bit later and since the match had obviously finished, I assumed Jokavic had won.
I have just listened to the end of the Final's first set tie break, so will wait for a while before turning on again.
