I'd like to live to 150 or 200, if I could do so with good physical health. The part that interests me though, is how I'd handle all the changes in society that would take place over such a long period of time. Taking the example of a 200-year life - if you were getting ready to meet your maker now, this means that you would have been born in 1814. Just think of the extreme changes in society and lifestyle that have taken place since then. You'd have to be a particularly adaptable and nimbly-minded person to deal with all that change, but I'd certainly like to try.
