Generational Gap

As far as the Book of Mormon goes, generations are counted about once ever one hundred years. Today, we throw them out all willy-nilly every couple of years. Right now we've got the Silent Generation, the Baby Boomers, Generation X,* Millennials, and Generation Z all roaming around the country.** If there had been this many population groups in Nephi's time, people would have had to lived as long as Methuselah!

*They should have just stopped naming generations after Gen-X. I mean, you're not getting a cooler name than that.

**And this doesn't even count the group of kids born after 2012 who haven't even been given a generational name yet.
