Psychologists say that 66 percent of women will end a budding relationship if the first kiss goes awry, while only 59 percent of men place the same emphasis.
So what, exactly, is in a kiss?
This is the subject of Sheril Kirshenbaum’s new book, “The Science of Kissing.” In it, the native New Yorker explores everything that goes on between our lips — from the hormones to the history.
“Kissing is a powerful experience,” said Kirshenbaum. “It engages all the senses: Scent, taste and touch are all sending information to our bodies as to whether it’s a good match or not. It’s nature’s ultimate litmus test.”
