Humans are social beings. We need to be in the presence of others. We need community and we need to connect. Being together, physically, allows us to communicate in ways beyond the confines of the computer screen. There have been studies that indicate that somewhere between 70 to 93% of all communication is nonverbal. We notice everything: how physically close someone is to you while they speak; microexpressions (your words may be saying one thing but your face could be saying something else); posture; vocal tone. I’m speculating but I would assume how someone smells affects us as well – the unconscious mind may pick up the scent of stress. We are visual and tactile creatures and ultimately animals so we notice what is unsaid as much as what is stated.
