what does the eye doctor expect when he asks you to read the letter chart at an eye exam?
Should you only read the line if it is clear? I can probably read all the way to the bottom of the chart because I know my letter shapes. Does he want me to read the blurry ones too?

does the life expectancy of humans have a ceiling? will people in the future live until 200?
Obviously I don't expect people to predict the future, but I'd love to hear more educated guesses than mine. Over time we have continuously gotten older and older, due to better medicine and technology. Have we reached our peak? Or is it possible for people to keep living longer
