A dark caption.

The doctor scribbled some notes on his paper as he looked at his latest subject. Oliver Masterson, 79, an old man he had met and offered him a chance for a longer life, now with the body of an unknown woman, judged to be in her late twenties. She had come into a clinic he had worked out previously and was deemed perfect for the procedure. Once she had been properly sedated and transferred to his control, he was able to perform the surgery.

It only worked one way, sadly, the doctor thought. It would have been very interesting to see how she reacted to having the body of an old man below her neck, but he would have to settle with this instead. Still, his latest experiment had done all it had set out to do and if nothing else at least Oliver was much younger and much more attractive!
