Hey kiddo, do you know what senescence means? It's a big word that means getting old and ageing. When we get older, our bodies change and we may not be able to do the things we used to do when we were younger. However, scientists are studying ways to slow down or even stop senescence. This is called "negligible senescence."
Now, if people could stop ageing and live for a very long time, it would have some big effects on society. It might mean that people would work longer and learn new things for much longer too. They would have more time to pursue their dreams and passions.
But it might also mean that the population would grow much faster because people would be having babies for a much longer time. The earth could become more crowded and there might not be enough resources for everyone.
Negligible senescence could also change our ideas about death. If people stopped ageing, there may no longer be a "common age" that people die. This could make it harder for society to figure out when people should retire or when they should be considered "old."
In summary, negligible senescence could offer many opportunities for people to live healthier and accomplish more in their lives. But it could also raise concerns about overpopulation and could lead to changes in how we think about ageing and death.
