During an interview, one of the key things you have to be aware of is your handshake. A good one — not too hard and not too limp — projects confidence and capability. There have been studies that show that great handshakes lead to higher chances of being hired. Now, some new research from a study that followed more than 50,000 people over 43 years has revealed that people with stronger grips have longer lives, according to Bloomberg. It's probably because the strength of a handshake is a good indication of how physically strong you are.
Who knew that a handshake could reveal that much about a person?
