Really?
Imagine you are in unbearable pain every moment of every minute of every single day for the rest of your life. Moving hurts, breathing hurts, the slightest touch from a loved one -- a kiss or hug -- inflicts so much pain you can't stand it. And all the while you are bound to your bed. You can't go outside or have any self-autonomy. every day is exhausting and sleep is impossible without heavy sedation. The painkillers are having less of an effect day by day and the little energy you have is all spent trying to cope with the enormous stress of this burden.
You don't even have the energy to carry a conversation with the people you love. Even the act of trying to consume food is pure torture.
Would you go on regardless? Would you live a happy life when the doctor comes in and forces a tube down your throat to infuse you with nutrients just so this life of suffering can continue?
What happens when we find the technology that will make it possible to extend life almost indefinitely?
