When two people have a close bond, their heartbeats synchronize in a process called "entanglement," The Daily's Justin Rocket Silverman reports. Silverman then uses this information to creep out three dates.Research Ramesh Rao told Silverman that entanglement "is a surprisingly accurate measure of how much two people are connecting--both physically and emotionally." A nervous date will have a fast heart rate, a date who's feeling it will chill out, making her heart rate flatter. So Silverman measured his heart rate and then "was set up on three blind dates and instantly ruined the mood by asking each woman to wear a heart monitor called the Polar RS800CX." The ladies' hearts, alas, were just not into it. Surprise. The blonde's beat too fast, the Los Angeles native's was too slow, and the "penciled-on eyebrows" girl was just not Silverman's "scene."
Nevertheless, Rao wants to start a website where singles can upload their heart rate files to scientifically prove true love.
