This week Justin and Brian finish up their discussion on Meg Jay's book The Defining Decade. They look at the final section of her book devoted to biological realities during the decade of one's twenties. Simply put, these are biologically the most fertile years for men and women from a biological sense, and what you do with you body in your twenties really matters. With the prolonged delay our culture is seeing in terms of having children, this has massive implications that many young adults do not realize. Justin and Brian try to discuss some of these implications and offer the Bible's perspective and hope when it comes to these realities whether you are single, dating or married.
