#13 Feet – The Body Part That Gets Tickled The Most
The sensitivity level of any body part that responses to tickling is known as the tickle response. There are many studies done to find out what makes your feet, underarms or any part to tickle.
A foot contains about 8000 nerve endings that makes it a very sensitive part of the body. These nerves act as a receptor for touch and pain responses. This is one of the main reasons why tickling happens as the nerve endings are quite close to the skin.
