Doc:
On the prayer front, I've got you down for one sick mom and one new job. Got it. What's your mom's name, by the way? (I'm asking only for anagrammatical purposes.)
On the reassurance front, I'll chime in with a brother-in-law in his 50s and an aunt in her 60s who underwent the full triple-bypass procedure with no problems. As has been already mentioned, the fact that they're catching it early makes it that much more safe. (Plus, from what I understand, Angie O'Plasty is nowhere near as scary as she used to be.)
On the light-hearted humor front, this guy's sitting at a bar with the saddest face anyone's ever seen, moping disconsolately in his beer. The bartender walks over to him and says, "Hey, you look a little down, buddy. Want to talk about it?"
"I guess," replies the man. "I just found out something terrible about my wife. I've kind of had suspicions that she's been cheating on me, so today I left work a couple of hours earlier than normal, snuck inside the house, and sure enough, she was up in the bedroom having sex with my best friend. I mean, bad enough she was cheating on me, but with my best friend!"
"Gee, that's terrible," says the bartender. "Here, have another beer on the house. So, what did you say to this so-called 'best friend' of yours?"
"I walked right up to him, looked him square in the eye, and I said--
(Spoiler space so you don't accidentally read the punchline too soon)
"--'BAD DOG!'"
