On one hand, there is positivity in the current viewpoint. The main advantage is that people can spend more time with their loved ones. Because of having more time to live, people can enjoy the simple things in life and gives them the opportunity to strengthen their relationships. Another great advantage is that it can boost the economy, because people have more time to be productive, which will help the financial process grow.

However,  not everything has to be good. For example,  higher life expectancy may cause overpopulation, which can be devastating towards the overall growth. Another serious issue is that the work force will decrease over time ,  because then when they retire, there will be less of the youth to take over their work.
Overall, I think that the disadvantages overweights the positive impact. Because even though there is a positive side, it will cause a lot of problems in the long run.

On the one hand, having more time is a luxury for some, work and tight schedules mainly being the problem. For instance, many articles all over the world reports on cases of people that were burnt out so much so that their lives ended up being taken early on. As a matter of fact, this event would make people much happier as they have more time to spend for them selves and their loved ones. Speaking non increasing life expectancy science-wise, the way humans develop would also change, with a possible chance to be younger for longer, which in question is the stage when both your physical and mental health is at its prime.

On the other hand, though, the human population all over the world will rapidly increase. As a result, the demand to expand more for the growing amount of citizens is bigger than the time they have to to do so. Overpopulation is already a big eight problem now, but with this step, it will become even bigger,
