What would it be like to live a thousand years?

That's the time from the Dark Ages till now. You'd have over 10 modern lifetimes. You'd have to work for how many of those years? Could you not work them? You could be a fireman, policeman, ballerina, doctor, lawyer, engineer (both train and civil), sailor, teacher and whatever else. What if all you could be was a ditch digger? Could you be a ditch digger for a thousand years? Could you make lattes or bus tables for a thousand years? Everyone you talk to, "I know, I know, I know." What would it be like to be 800 and be dating someone 200? Would science stagnate because everyone has all of their good ideas in their 20's? What if Octo-Mom wanted to have even more babies? What would we do with all those people?
