Would people be happier if they could live forever?

These days, you can live much longer than those in the past, and many of you seem to be happy about that. However, when it comes to living forever, I believe you would not be happy any more. Living forever means you would never die, and it means you can try anything over and over again, no matter how many times you fail. This repetitions might not be fun or exciting for you, since in most of the cases, it is the fact that life is short and limited, which makes your lives thrilling.
In addition, the longer you live, the more stress you have. It is true that you would be able to enjoy a lot of fun things if you could live permanently. However, this could not make up for many bad things that would happen to you.
