He's recovering okay? I guess? He hasn't got as much energy as he's used to, and it's endlessly frustrating to him. But other than that, he's doing fine, or at least as well as can be expected. No problems other than the "oops, almost died" part, and the "oh, and now you have the stamina of a kitten" part. Only, when kittens are too tired to climb a flight of stairs, it's cute, and someone carries it; when a 6'2 man is too tired, nobody offers to carry him instead.
It's gotten me to look into the possibility of writing for money because I'd like more time at home.
