Darwin wasn't totally off-base in his hypothesis, but the part about tickling being related to humor missed the mark. He also posited that we're ticklish in places where we aren't usually touched by others.
People may be ticklish tickling spots that commonly produces a tickle reflex to varying degrees -- or not at all. Others may be ticklish in places where most other people aren't. The soles of the feet and the underarms are two of the most common ticklish places on the body. But the feet's ticklishness fits nicely with Darwin's theory, since the soles of the feet are accustomed to diffuse pressure stright bait the rest of the body when we're standing or walking [source: You probably won't get much of a response if you try to tickle the sole of another person's foot by pushing the open palm of your hand against it.
What's more, the soles of the feet underarms a high concentration of Meissner's corpuscleshighly sensitive nerve receptors located close to the skin's surface [source: These nerve endings make underarms feet extra ticklish. As we saw on the last page, the most common ticklish spots tickling also often those most vulnerable to attack, at least around the upper body.
Your underarm contains the axillary vein and artery, and it also allows unimpeded access to your heart, since the rib cage no longer provides protection to the chest cavity at the underarm. The same goes for another ticklish spot, the neck. Without protective bones in either place, it would make sense that we would reflexively react to another person touching those areas.
Write to me in PM, we will talk. You are mistaken.
Idea good, I support. Quite right!
Write to me in PM. You commit an error.
I know, that together we can come to a right answer. Just that is necessary. An interesting theme, I will participate.

I will be free - I will necessarily write that I think. I can not take part now in discussion - there is no free time.
