That's interesting. Those words could actually be used if and when the regen limit is exceeded.The first Doctor's last words were to have been (according to the camera script), while alone in the TARDIS and talking to the console:
"No, I can't go through with it... I can't..." At which point the Time Rotor starts moving, forcing him into the change. But they were dropped due to pressure of time in the studio.
Ah this coming from the person who complains when people "Attack him" instead of debating.
