For many years now I've (half) joked that I intended to live forever and that so far, it was working out OK. Time has passed though and although I'm a great deal fitter and healthier than most people of my age there were a few nagging health problems which were tipping my life out of balance. It was time to look for a new approach and as so often happens, the reviewing gods brought me the book I needed. ''Live Forever Manual: Science, ethics and companies behind the new anti-aging ageing treatments'' seemed like the answer to my problems - only you get so much more than just 101 tips.
There's a discussion of whether we can live forever and whilst ''forever'' might seem like a big ask right now, I think there can be little doubt that much longer lives are possible in the near future and that what we should now be looking for is 'escape velocity' - curing our present problems and pushing us on until wider-ranging solutions are available. This is obviously more attainable for younger people, but there's no reason why people of my age (I call it upper middle age) shouldn't be living more years when they are healthy. Lifespan would obviously be of little use without a decent healthspan.
