If People Lived Longer.....

I think people must live so much that they are suppoused to.I don't want to die young but don't want to live more than 70 years. Because life will be more difficult at the older age. Technologies are developing every day and it was evident that one day doctors will use such technologies that will make people longer. Life won't be interesting if everyone lives for example at the age of 100and more. I suppose that some people want to live so long but I am not one of them.
