At what age do you think people should not have kids

Chan • Me and my partner are ttc have been for 11month, living together and more than ready to start a family
I've seen enough now, people doing polls about young mothers. Always picking on them. Now I think it will hit a certain age when people shouldn't have children. E,g I believe 45 you shouldn't have children because time they're 16 you will be 60. Silly poll but see how oldies like to be picked on.
