I would not like to live 250 years because of too many changes that will occurre at that time. For the first and most significant most of the people that I love will pass away. Sometimes the death of our loved ones takes all the will to live and nothing is the same anymore. Secondly, during this time the world will evolve a lot. Discoveries, environment, technology - life will look completely different and it could be hard to get used to it. Eventually, I think that 80 years is more than enough to do everything you want from life and even get bored. Many people dream about being able to live much longer but for me this amount of changes will be too much to handle
