Warm hands
Subconsciously, cold or clammy hands are a sign that we should not trust this person, or that we need to keep our boundaries up when we first meet them. But if you have warm hands, you immediately are ahead of the game and come off as someone who is more open and approachable.
Shaking hands is something that we all have to do from time to time, even though the fist bump has become popular, the handshake still dominates the world of business and many others. So make sure to rub them together before shaking someone else’s, it could make your life a little bit easier in the long run.
