I've thought a lot about death, mortality, living in a futuristic world, etc.. I would immediately sign up for immortality instead of dying in ~70 years given the magic pill rule scenario. Just think of all of the amazing things you'll witness while not having any forced pressure for all aspects of your life. You'll never get sick, you'll never need to worry about finances because there's nothing that would put you into a fear driven scenario where you "must" make money. You could go through the years doing whatever you want and you'll live long enough to escape technology bubbles that each generation lives through. Like you said, you're pretty much a different person than you were 15 years ago. If you were 150 years old but still 25 inside, you'd get to experience a completely different world. It would be like having infinite lives with no reset switch on your memory.
