I think technology is the biggest reason humans can live longer. Because of technology we have the resources and medicine to help cure or help people cope better with a certain ailment they have. For instance how people with missing limbs can have a tougher time than most so prosthetics are there to help them, technology is growing so rapidly that in the near future we might be able to either regenerate certain limbs or create robotic limbs that can make it seem you never had a missing limb (If anyone played Spiderman Ps4 with Otto and Peters research on a arm that would help people with missing limbs, something like that). Ignoring the fact the scientists in that world turn into creatures.
Another example would be right now how doctors and scientists are trying to complete a vaccine on the pandemic that is happening. I think in the grand scheme of things technology is forever expanding to the point it might be scary to some and exciting to others that the limitations of people, animals, etc can be non existent because of technology(i.e humans cant fly- buy a jetpack). I know scientists now are looking at cloning, but what if they are trying to find DNA in animals that can benefit humans. Technology is endless so anything is possible.
