(ALBANY, NEW YORK) The strength of a man's handshake can tell you a lot about his physical health and sexual aggression. Researchers at the University of Albany tested the handshake of 82 men and 61 women. They also gave them a medical physical and took their sexual history.
Here's what they found: Your hand grip strength is an "honest signal for genetic quality in males". A stronger handshake also correlates with losing your virginity at a younger age and being more aggressive in the bedroom. What about the chest and/or fist bump? What if you like to high-five? Many questions are still unanswered.
