To reach the 'eternal' conclusion, the professor investigated love and romance among baby boomers aged over 50. Professor Barusch found that the people she surveyed "consistently reported that love improved with age," the Salt Lake City Tribune reported.
She found a wide range of romantic experience when she interviewed 91 people aged 51 to 97 - most of them widowed, but also including married couples and divorcees, reports the NZPA.
The researcher kept looking for a natural 'cliff' when romantic experiences became consistently different but didn't find one.
Flexibility was prompted by intimations of mortality: some older women had no reservations about initiating relationships with younger men, even if they were raised with a different set of cultural mores, the researcher found.
