Our species has survived for millennia because women selected mates that were providers and protectors and men selected mates that were healthy enough to birth and feed her children.

Awkwardly, technology and modern society has made it so that our biological desires are no longer useful for selecting a mate. This explains why someone like Ronaldo is very desirable in our world. He meets the biological desire of athletic and tall and also meets the logical desire to be with someone who makes a lot of money.
