Cory Doctorow's writing that gives you REAL HOPE that the future will be a good and happy place, and that you might have a chance of making it to that point. Aubrey de Grey has been studying gerontology (the science of ageing) at Cambridge University and he proposes that with some science and engineering smarts, we can make huge progress toward extended lifetimes in the time left to even old farts like me (not quite 50 yet).
