As life span increases, which it will in the next few decades, so will the length of fertility. So any extrapolation out 80 years is nothing more than sensatio

As life span increases, which it will in the next few decades, so will the length of fertility. So any extrapolation out 80 years is nothing more than sensationalism. I truly don't understand this nonsense. We can clearly see in the past 80 years, the really slow moving pre internet past, the global fertility rate has changed how it works significantly, but suddenly in this hyper-society we are wasting time looking at 2100?
