everyone's parents will die sooner, putting stress on the young adults of tomorrowWhat impact might the trend of couples having children later in life have on our culture? Why?
Well first of all I would think that it would benefit our society/culture because with age comes wisdom and patience. Also they are most likely educated people hence the choice to wait, and with education people make healthier choices.
less kids because you start having kids later, therefore less time to have kids. Cummon think about it! also, less parent-child involvment, because the parents are older and less likely to participate in their children's lives then they would if they were younger.
I think it would establish a new norm to wait longer for marriage and/or having children. It might also make 35 the new 30.
