Do you understand what's about to happen to you?

I asked the subject as he sat in front of me, nervously twiddling his thumbs.

He looked down at his feet, avoiding eye contact.

Nevertheless, he nodded diligently in agreement.

I need you to tell me, Jason, to make sure we're on the same page.

I continued.

At that point, he lifted his head, and I could clearly see the horror in his eyes.

He had agreed to our experiment.

But despite his initial enthusiasm, I started to wonder if he wanted out.

Please tell me, I asked.

You're going to kill me?

He said before looking back at his feet.

I helped the contract in my hand.

It had been a lengthy process to gather a volunteer that also fit the requirements

of carrying a terminal illness.

Jason, at the age of 30, had a lethal brain tumor that would kill him within months.

Making him the ideal subject.

Yes, but only temporarily, I explained.

What if you can't bring me back?

My side.

We've run multiple trials, and I can assure you that you're perfectly safe in our hands.

We wouldn't do this unless we were absolutely certain.
