On the one hand, if we could have such a long life, we would be able to have more time with our friends and relatives. We could start more projects during our lifetime and meet more people.
However, we don't know in what conditions we would live our last years. It could be able to stay alive that time only being in coma or resting in a bed. In addition, we would see many of our loved ones die in our lifetime.
To sum up, I would say it is preferable to live as much as possible, but it isn't the only thing that matters.
