You and your wife will be in my thoughts and prayers. My own wife underwent emergency heart surgery about 6 weeks ago. Thankfully, she is doing well and recovering nicely, but it gave us quite a scare. I can also tell you, that even thoughyour wifemay be in a drug-induced coma, she is still able to hear things going on around her. Talk to her, read her books, tell her how your day went, anything to keep her stimulated. This will assist in her recovery.
For the rest of us, don't take what you have for granted. Tell your spouse, significant other, partner, etc., how important they are to you every day.
Again, my wife and I will keep both of you in our thoughts and prayers. Take care and God bless.
