Daniel woke up like this and by the time the nurse came in and saw him, he was already out of bed. Despite her years, the things she's seen, her first reaction was to scream, alerting the rest of the staff.
He learned the details from this doctor. His body and her head were nowhere to be found.
"Whose body do I have?"
"Your head was attached to the body of a Mrs. Miller, age twenty-five. Congratulations, you are now forty-five years younger."
While he smiled at the doctor, inwardly he was a bit alarmed at how the doctor was going about this. Shouldn't he be more concerned about this? Of course, maybe his demeanor was to keep things cordial, which Daniel did understand.
As the doctor talked, Daniel found out that this was, as of right now, permanent. He'd have this body the rest of his life. He'd now go through life as a woman.
Oh well.
