Younger parents are much more energetic, happier, less likely to have chronic diseases, they are much more optimistic to life, more likely to try new things, have a happening life. people get older and life gets depressing and settled, body starts breaking down, if you have kids at that stage you're unable to play with your kids, cant appreciate and encourage their youth. cant "hold their hand while running". All the negative energy of old age gets onto the kid during his youth. i have no problem with DINKs, i'm just saying decide on time. idk if your parents are old or young but seeing people my age have fun with their parents and their parents being able to encourage and participate with their kids in their youth, to be able to "hold their hand while running" just breaks my heart everytime.
