Thanks so much for your inspirational reply. It sounds like you went through a LOT more than I am facing.
Frankly, the only problem that I've had with heart surgery is that they have to saw your sternum open and then wire it back shut.
At that point...which is where I'm at... they tell you not to lift anything or do any tasks which might cause it to open up again until it has healed.( If it opens up then you are really screwed )
No one can tell me how long this typically takes. ( I don't think they deal with too many rock climbers). I was hoping someone out there had been through this.
