Age, apparently, is only a number. According to a recent study published in the Journal of Family Psychology, most parents do not consider their 18-25 year-olds to be adults. And the kids agreed. These "emerging adults" are taking longer to settle down, marry and become parents, creating a new stage that did not exist in earlier generations.
