From all of us here at Prosblogion and the readership I'm sure: Get well soon!
First, Al did NOT have a heart attack. If you hear that, it's not true (and it's false if you didn't hear it). On Friday, Al had triple bypass surgery to remove some blockage. By all accounts he is recovering well.
When I was with Al for an extended time a little more than a month ago, he was quite vigorous and in great shape, so I can't imagine what super-powers he'll have when his recovery is complete and he has achieved maximal health.
Atheists and agnostics, it wouldn't *hurt* if you sent up a few tentative or conditional prayers to join the rest of us! ;-)
