A Wii rest

I have taught on two weekend study schools and examined three PhDs in the last 10 days, in addition to the usual round of writing, marking, admin, reviews, meetings (and more meetings), responding to students' emails and making research visits to schools etc., so am feeling in need of a bit of rest & relaxation. I am thinking of buying a Nintentendo Wii to play with this forthcoming weekend...along with half of Britain, it seems. Now I have to get in the queue behind physiotherapists, who are using them with recovering patients. I was already way behind care home residents in the Wii stakes. Anyone for tennis?
