I'd love to see myself, to go through this at least with a strong body, even if my heart is no longer with me. Truly, I'm no longer in charge of my inner self, or even my emotions. Nevertheless, I can still command my limbs to do things at my will.
But a man is made of two things: body and soul. If the soul ceases to exist, every single time being overruled and overturned by coherent reasoning, then perhaps the body will have nothing to hold onto. Indeed, a lifeless life.
