No. It could at best defer the health costs. We need to stop being passive about this and embrace the idea of (1) life extension technologies for those who want, (2) assisted suicide for those who don't. When this philosophical shift happens we can get much more serious about life extension research and mental well-being (purpose; reasons to live) and reduce the vast expenditures on palliative care for those who are merely waiting around to die.
