Why Are Some People Ticklish?
Tickling can be a fun game, a temporary annoyance, or a deeply unpleasant experience, depending on a person’s tickle response.
People vary in how sensitive they are to tickling. Some people are only ticklish sometimes, while others are not ticklish at all.
Scientists have discussed the tickle response for hundreds of years, yet researchers are only just beginning to understand why some people are ticklish, and what purpose this strange response might serve.
