Everyone's talking about declining fertility but nobody's talking about declining energy. Raising children is hard work, at least if you want to do it all yourself and do a good job. I wish every day that my body was 20 years younger. And I wish my parents were 20 years younger too, they'd be a lot more able to provide support and enjoy their grandchildren. By the same token I'll be quite old when my kids have children, if I even live to see it.
