The space shuttle Columbia exploded while I was in a seven day medically induced coma. I watched the memorial service when I woke up. It actually took a while for me to realize I had no idea what happened. Similar experience with the Boston Bombing. I was having my right hip replaced while it happened. Balloon Boy happened while I was having surgery on my broken right hip. Sandy Hook while I was having my left hip replaced.
On a brighter note, my ex-wife at the time stood beside me the whole time and no we are back together and closer than we ever were.
