Immortal?

We were on the subject of "aging" the other day in a Pathobiochemistry lecture, and we basically talked about what exactly makes us age, and what conditions have to be fulfilled by a cell for it to be immortal. As the lecturer was talking about how scientists discovered why hydra (A minute freshwater coelenterate with a stalklike tubular body and a ring of tentacles around the mouth) show no sign of senescenece or mortality, which was that they could replace every cell in their bodies with new cells, there was this sentence that particularly caught my attention:


Even if (the replacement of every cell) achieved in humans by engineered stem cells, replacement of neuronal cells with change mind and wipe memories...


Imagine that you're offered immortality in exchange of your mind and memories... do you wanna live forever? All the sweet (of course, and bitter) memories will be wiped away, just so that a mere physical body could live on, and all the personality and talents that make you the unique you would be altered... that sounds like a body without a soul to me. And that, isn't a real life. 


Oo.. and then that reminds me of this, though not quite relevant... 


And what do you benefit if you gain the whole world but lose your own soul? Is anything worth more than your soul? ~Matthew 16:26 NLT
