“What I want to know is why folks in the Old Testament lived for hundreds and hundreds of years and today seems that eighty years is the norm.”
Daylight Saving Time? ;)
I had it explained to me that ‘time’ was a different concept back then and that a ‘second’ to God could be eons to we humans...or something along those lines.
All I know is that I certainly do NOT want to have a child when I am 90 years old, with a 99 year old husband, most likely also in diapers, as did Biblical Sarah! :)
It was likely a genetic thing.
“Indeed a genetic basis for longevity has been demonstrated in animals, e.g. fruit flies, such that genes for longevity can be lost from a population.”
“Recent advanced computer simulations vindicate this proposal, showing that an exponential decay of lifespans fits well with accumulating mutations after the catastrophic population bottleneck at the Flood.”
