A neuroscientist says there will be a medical test that can detect if people are really in love by 2028.
Doctor Fred Nour has written a book about love and says the test will use an MRI-style machine to look for certain chemicals in the brain.
Those chemicals, called nonapeptides, show up in large numbers when someone is in love. That's the theory, anyway.
Nour suggests that one day partners might opt in for pre-marital scans before saying "I Do."
