I would do it. This isn't infinite life, this doesn't remove the stakes. It's just more time to accomplish whatever I wanted, more time to live life to the extreme, more time to re-read the cosmere for the hundredth time. When I'm done (centuries from now) I'll just start living more recklessly, checking dangerous and crazy things off my bucket list until I die. I don't think this removes the value from life, because life is still limited. There's just more of it.
