I AGREE: It’s Not Immoral To Want To Be Immortal: Fears of a world of geezers who hog up all the resources are overblown. Of course, immortality isn’t really the point — even if you never age or get sick, eventually you get hit by a falling safe or something — but living much longer and much better is.
Plus, as I’ve noted, longer, healthier lives can bear huge economic dividends.
