As an American I dont think a handshake = touching. A handshake is such a common ritual that I barely notice it. If someone touches me on the elbow or wrist, I am instantly aware.

Isn't that exactly what this article is about? In other cultures "Did you touch each other?" might get a "no" response even after a kiss. In others, people who look at each other longer or more often than is the norm are forced to marry or will be tried for adultery (or be attacked for showing insufficient respect)

If you'll permit my analogy, a handshake is to a signature on a form, what a hug is to a personal note. Completely different.

There, fixed that for you. ;)

Heh. Thanks
