Why are you ticklish and what does it mean?

Ticklishness is believed to be a complex response involving both physical and psychological elements. It likely serves as a social bonding mechanism, promoting playful interactions and signaling vulnerability. The sensation is thought to arise from the body's response to light touches on sensitive areas, triggering laughter and reflexive movements. Ticklishness may also indicate a heightened awareness of one's surroundings, as it can help individuals react to unexpected stimuli.
