At some point, you're brain's going to begin deteriorating, and you're going to be surprised to discover there was no household electricity during the time of Jesus, like a friend of mine who was born in 1930 (He still has an adult mind and a fair bit of intelligence, but he occasionally has episodes like that.), but wouldn't it be possible to create a system where a heart attack is unlikely to be fatal? If there's a blockage in the heart, another device would take the place of the heart while the individual is taken to a hospital to remove the blockage and clear out the arteries around the heart. I always wondered why they couldn't just constantly revive someone until I realized you can't just restart a blocked heart. That friend of mine is also beginning to go blind. He only has peripheral vision in one eye. At some point in the near future, bionic eye technology will become advanced enough to give people a general idea of what's in front of them. I imagine he could get a decent bionic eye if he survives the next decade.

What's the future going to look like for life expectancy?
