I had the privilege of being interviewed by rtve (@rtvenoticias.rtve.es ), Spain’s national public broadcaster, about our research on fertility desire and romantic partnership. The interview was a live radio show and now it is online (2:15-7:45): www.rtve.es/play/audios/...

Have you heard of the Fire Horse Year? In Japan, fertility dropped 26% that year & jumped 41% the next — the biggest change in world history since 1950. The reason? A widespread superstition related to the Fire Horse Year. I just spoke about this in an interview with @financialtimes.com
