Healthspan and lifespan of people is continuously improving, and I am hopeful the science has just started. Maybe in 2100 people will be as able at 70 as they're at 30 now. Maybe many people will grow old and unable, but then scientific development will let them cure themselves, and have a second life of sorts. I donate to Lifespan.io in the hope of this.
