First date last night? Now AI can reveal if it went well...or if your date found you boring

Worried your Valentine's date hasn't gone well? An app could soon tell whether a second one is on the cards… or if they simply found you boring. AI can now work out how well dates have gone by measuring how much each person is sweating, how quick they're breathing, and how fast their hearts are beating. The more these synchronise, the more likely the two people involved are compatible, according to the study by the University of Cincinnati. Scientists behind the technology are looking at developing it into an app that can give romantics'honest feedback' about their dates – or themselves.
