Yes, my insurance covers 36 weeks of cardiac rehab, which I will certainly do.
I kind of have the best of both worlds. I retired a year ago, but work back as a consultant, pretty much half time. Stress is like almost zero since I am no longer in charge of any programs, or people, OR trying to climb the coporate ladder. I have a very quiet office area in which I go in, sit down, and basically just use my head. Other than walking a few hundred yards, it really is not much different than being here at my home computer.
So ... given that, and barring complications ... sounds like 6 weeks might be doable.
