You are already extending your life by going to the doctor. What's the difference between that and an anti-aging therapy? How is that even controlling your death? You are going to die one day. It's a fact. How do you want to die? Would you rather die in the worst conditions possible, like it happens to most people nowadays? If you are happy about dying like that, you might as well stop going to the doctor. Fact is, even if you don't realize, we have been 'manipulating' death for a long time. I think what's egotistical is your comment, honestly. You are basically opposing to a therapy which would remove plenty of suffering from the world, starting with reducing the chances of cancer, removing Alzheimer, etc., yet you don't want to remove it because evolution decided that living indefinitely was not advantageous for human survivability, and so we should not touch that. Heck, what's the point of technology if not to improve our daily lives? Should we oppose to all technology?
