If he was a marathon runner, it would present problems........the cardiovascular system is overengineered a bit, and can, just like your house, handle some clogging in the pipes with no real damage.
Very glad to hear that your Master is doing a bit better...I can only imagine how difficult this must have been on you both. Like the other people here, I send my best wishes for a full and complete recovery.
Will send lots of good thoughts your way. Hang in there- and thanks for keeping us updated.
I'm not seeing Master today after all. I am hoping He gets some well needed rest, and enjoys the day with His loved ones. Though I am looking forward to seeing with my own eyes He is well.
