It is highly disengenuous to say 'but men do it too'
the article is about a woman having a baby on her own.
If a man had a baby on his own, and the woman wasn't around, then it would be the same. But that is a very veyr unlikely scenario isn;t it?
I think it IS selfish of men to have children when they are in their 70s, but the mother is going to be around to do the ongoing parenting after he dies.
In the example given, there is no-one to share the parenting.
My mum is a very fit and healthy 80. There is no way she could be a full time parent to a 16 year old.
