Lets make the youngest of them age 18. Which incidentally was James Monroe's age, Alexander Hamilton was 21, Thomas Jefferson was 33, Ben Franklin was 70 etc. (at the time of the declaration signing)
What kind of people do you think they would be if they were essentially born in this day and age? So Hamilton and Monroe would have been born in the 90s and Jefferson in the 80s, etc, for example. (You are not limited to my examples)
