Idea: In the 1950s, a Russian scientist was able to attach a dog's head onto another dog's body, and it survived for a few weeks. We should be able to do much better now. So if a person is terminally ill, we should attach their brain/head to a machine (i.e. replacement body) to get maybe a few months of extra life, and attach the body to a machine (i.e. replacement brain). The head/brain can live a little longer and have fun in virtual reality games, and the body can be used for medical testing, without worrying about causing suffering. Over time, as the technology gets better, the head can live longer and longer, to the point where maybe everyone who is old and/or has minor health problems will choose to do it, even if not terminally ill
