Would you let someone else control your body if it was the only way to stay alive?

Apologies to hungryguy, whose question inspired this.

So let’s say you are innocent, but are about to be put to death. You can stay alive if you agree to become a cyborg. Your body will be controlled by someone else, but you will still be alive inside it. Perhaps you will be allowed to spend some time in control of your mouth or eyes, or even fingers, on occasion, when your body isn’t being used by your owner.

What do you think you would do in this situation? How would you think this through? What considerations would you make? Is it worth giving up control of your body to stay alive? Why or why not?
