I’m 44 and don’t have childen. The ‘why’ is very simple – I just don’t want to.
And yes, it really is as simple as that!
I didn’t have a messed up childhood, I don’t have a ‘selfish’ lifestyle now, and I find it pretty insulting that people think those are reasons for not choosing to have children.
Personally, I don’t particularly ‘enjoy’ hanging out with children – I’m perfectly happy spending time with my friend’s children as they come as a ‘package’, but given the choice, I wouldn’t choose to spend my time with children, and prefer to spend my time doing a range of other things. These aren’t all supposedly ‘selfish’ activities (although I do enjoy biking, climbing, travelling etc), but also caring for others (they just don’t happen to be children).
As the majority seem to say, it really is an individual choice, and one is not ‘better’ than the other. The only things that do really pee me off is the ‘you’ll change your mind’ comments, along with ‘having children is the best thing ever’ (for you maybe, but not for everyone), ‘you only understand ‘unconditional love’ when you have children’.
For those who’ve said that they’ve carried on doing their ‘pre-kids’ activities – The only thing I have noticed is that amongst the folks that I meet doing biking / climbing etc – most of the guys have children, whereas most of the women don’t. It certainly seems to be harder, or less likely, for a woman who has children to do outdoor activities. Is probably related in some part to childcare responsibilities which do lie more with women than with guys?
