I hope you never get to know, or experience such thing, but for some illnesses like cancer, at later stages, even the strongest painkillers don't help with the pain. There are many illnesses which turn you into an immotile person, and if you lack a loving family ready to put up with anything, life becomes a pain no painkiller can relief. Death is a part of our lifes, and our bodies are ours, so I believe we should get to choose what to do with them. If I were to spend the rest of my life in bed, immotile, in need of the service of my loved ones, for years to come, I'd rather put an end, relieve my loved ones from the burden and responsibilities, and my body and soul from the various pain that the situation causes.
