In short: He’s recovering well, working on his next book (a collection of essays), and taking advantage of his mandatory time at home:
My balance is improving with physio exercises such as impersonating a stork standing on one leg. And I can ride my bike, albeit a little unsteadily on tight corners. Blood pressure still veers toward the high side, despite medication, and I’m under orders to avoid long distance travel or getting involved in controversy. Controversy? Moi?
At least he hasn’t lost his wry sense of humor.
