Useful Psychological Tricks

1. When a group of people laughs, each person instinctively looks at the one they find most likable (or the one they would like to consider a close person). 2. When you have to do something particularly responsible or requiring concentration, in short, something that usually makes us nervous, it's worth trying to chew gum or even eat something. This is subconsciously associated with a feeling of safety, because we usually eat when we are not threatened.
