Science has also improved the length of life in other ways. For example, the advancements in improving food quality and gaining additional nutrients is just as important. The fact that science has taught people how to kill bacteria and how to avoid it, has helped to keep people healthy longer.
What is so unique and often so important is the fact that people can live a longer and a healthier life. Science has helped more people than ever to reach the 100 year old mark. With these advancements, it is likely that people will hit that goal ever so slightly over the next decades.
