Head Transplant...Mind-Body Connection? A theoretical discussion 🤔

My husband was joking that he’s going to live to be 120, and one day they’ll just transplant his head onto a 20 yr old’s body so he can live forever lol. All in good fun.

But it got me thinking, hypothetically, if someone could survive a full head transplant, would they carry on living the same?? Would your soul travel with you? Would the cellular memory in your new body cause a shift in your memories? Emotions? Personality? Does consciousness exist independently? Or does it rely on the body?

I figured this would make for a thought provoking discussion. I’m usually quick to make up my mind about questions like these, but this topic really made me wonder...What do you think?
