As I've come from a rather dysfunctional family, I've chosen to NOT have children in spite of several offers while I was younger. Now that I'm at 52, I still get offers to do the baby-making...but I'm too old. How many of you get offers to do that? I say it's unfair that I'd be 70 by the time the kid graduated from HS.
I think the question isn't so much would it be unfair to the kids as opposed to you finding it unfair to you. I was older when I got pregnant and I enjoy many of the benefits markhas mentioned. I also think it was beneficial that I had already spent a long time "sowing my wild oats" so I wasn't envious that I wasn't able to do that any longer, plus I really wanted to be a parent. You mentioned choosing not to when you were younger so maybe it's not an issue of age ... maybe it's just a matter of you really knowing yourself.
Yeah, once a person gets past forty, they have to ask do they relly wan tto deal with a teenager when they are over 60?
I happen to have a couple of hereditary issues. I have a hereditary eye disease and also an autoimmune disorder. I toyed with idea of beign a parent until I realized I'd be passing on "bad genes" to future generations.
Being gay, I'd have to be very deliberate about becoming a parent, but i decided not to.
