Key words Good Health.
My experience while outside the norm, was a tough go from the time i woke up. Had i still had 2 legs, i'm sure it would have went much more smoothly.
The hospital and rehab were impressed how well i was moving along, considering the limitations i have. Even in good health some are up and running the next day, while others have a more difficult time.
Either way, being prepared for potential for issues, yet having the ability to move on faster never hurts.
You'd be surprised how limited one can be, when they cannot apply too much pressure, or lift more than 10 lbs, for x time frame.
