We're suffering from a demographic winter. As there are more older people around without younger people to replace them, we're having an older population on earth and will necessarily be fatter.

[Mrs. Don-o]

I agree with you that we're in the midst of a demographic iner, especially in Japan, the EU, and the Anglosphere.

But I don't think an ageing population necessarily means a fatter population. Serious question: are the Japanese fat?
