Well, I got to MGH at 6am (first in line, no waiting) and it's now 1pm and I'm back home. Procedure seemed clean and efficient to me (from what I could see, being unconscious for most of it). The only major problem being the constant question of do I really need to go to the bathroom or not.
Now it's to bed to try to sleep off the anesthesia. I'm sure I'll come up with some up with some sort of philosophical implications of all this. But it's going to be later.
Thanks to all who have been so supportive. Check you later.
