You can hardly find the person who has never thought about eternal life. There are a lot of advantages and disadvantages of living forever. But what if we are able to live 200 years? This is a dream, but a lot of scientists work out to make it real. They set up different experiments and step by step  they become closer to this level. To my mind, if they prolong our life, the progress will not come up. One generation will be 
\slower than three. So, I think it's better to find out the way to accept the terms of our life and to calm down the grief.
