London, Mar 25 : It takes 8.2 seconds for a man to fall in love at first sight, say scientists.
What''s more, if a man''s gaze is more like four seconds, research suggests, he is less than impressed.
But if the eye contact breaks the 8.2 second barrier, he could be in love, say boffins.
However, women treat both hunks and geeks alike, with their eyes lingering on both for similar amounts of time, reports The Telegraph.
