Science has begun to find out  the mechanisms of biological aging and  the possibility of extending the lives of people beyond one hundred years. The question is to know the (social and personal) price to be paid for achieving this life:

 On the one hand, we could get bored of life. At some point, we've traveled every corner of the world. We would have done any imaginable hobbies and enjoy finding new hobbies seem pointless. In addition if we live longer we will  have to work harder because the retirement age would rise.

On the other hand, we would enjoy more years so we can spend it with our family and friends. And live longer also means that we have good health, and if more and more people live longer, this will mean that the quality of life in the world has improved .

 We would  like living for 100 years, but it is more important to add life to years and not years to life but the most important thing is living with health and this is achieved with a balanced diet and moderate exercise.
