The popular saying "Life is now too short to...." brought about this topic to my mind.
Let me be concise.
There are claims that Qur'an and biblical characters lived many years.
Adam; claimed to have lived 930 years.
Methuselah; 969 years.
Seth; lived 912 years.
Enosh; lived 905 years.
Kenan; lived 910 year. Etcetera.

And any present generation that lived about 180 years will draw attention.
Some people now doesn't even want to grow too old. (like 100)

Is there any scientific explanation to why older generations lived longer?

so u deh believe those bible tales?
