Here is the link/quote from Eliyahu about this topic.
In this context a generation is a natural lifetime. Scripture rounds a natural lifetime off to a period of about seventy years; "The measure of our life is seventy years" Psalm 90:10 BBE.
Dawn you are just to fast I didn't even get a discussion going. You just came back with the answer just like that. You must have a good teacher ! LOL !
Shalom! May I join in? I have no problems with generations. LOL!

I agree, a generation is the course of an individual's lifetime, but,

Gen 6: 3 YHWH said-yet his days be a 120 years!!
Bro Eliyahu, and Dawn, 70-80 (general lifetime) is way too short!! Most healthy folks live past that to 90 and more!
Israeli custom wishes a person to live to 120 at birthday celebrations, and I'm totally for that!

How about "I shall not die, but live, to declare the works of YHWH"-Psalms 118:17.
In Hebrew, Generations is to-led-aw' meaning :-
descendants, results, proceedings, generations, genealogies, account of men and their descendants
genealogical list of one's descendants, one's contemporaries, course of history (of creation etc)
Thr root word is yalad, meaning to bring forth as in childbirth, to bear, to beget.
Adam's generation lasted down to 930 years, he lived to see the many, many, many generations of his children, grandchildren,
greatgrandchildren! Takes one's breath away!

Not to mention Avraham who lived to 175.
The way to go of course is live healthy as much as possibly can, in spite of the pollution (in every aspect) around us.
Blessings.
