Four out of Five do not wash their hand after using the toilet/washroom and from the ones who do care to wash their hands most do not wash properly so that is why I say only fools shake hands.

The correct way to greet is NAMASTE style where no contact is involved AND SO IS THE BEST WAY.

The Meaning of "Namaste"

Question: So, what does Namaste mean anyway? 

Answer: 

The gesture Namaste represents the belief that there is a Divine spark within each of us that is located in the heart chakra. The gesture is an acknowledgment of the soul in one by the soul in another.

Definition of Namaste

Nama means bow, as means I, and te means you. Therefore, namaste literally means "bow me you" or "I bow to you."

How to make the Namaste gesture

To perform Namaste, we place the hands together at the heart chakra, close the eyes, and bow the head. It can also be done by placing the hands together in front of the third eye, bowing the head, and then bringing the hands down to the heart. This is an especially deep form of respect. Although in the West the word "namaste" is usually spoken in conjunction with the gesture, in India, it is understood that the gesture itself signifies Namaste, and therefore, it is unnecessary to say the word while bowing.

We bring the hands together at the heart chakra to increase the flow of Divine love. Bowing the head and closing the eyes helps the mind surrender to the Divine in the heart. One can do Namaste to oneself as a meditation technique to go deeper inside the heart chakra; when done with someone else, it is also a beautiful, albeit quick, meditation.

Namaste allows two individuals to come together energetically to a place of connection and timelessness, free from the bonds of ego-connection. If it is done with deep feeling in the heart and with the mind surrendered, a deep union of spirits can blossom.
