A Really Short One
1. The Q in the previous quiz refers to the civilian way of greeting each other, which started in the west, and is used widely throughout the world today. The right hand represents the sword/active arm, and keeping that hand in use shows a sign of total trust and sends an I-Will-Not-Stab-You-In-The-Back signal (unless you are Nawaz Sharif, of course! :P)
The handshake has many stories and the wide range of the ethiquette is quite interesting. For more, go here
Ineterstingly, many people also believe that the right handshake was a part of the anti-left (left as in the left hand, not the ideology) revolution. The Romans were pretty infamous for this. But even here, the custom was justified on engaging the weapon arm.
2. The Baden Powell story is slightly different. It signifies why the *scouts* do not follow this custom. I was unaware of this till Silencer's post. Quite interesting, that one. Thanks! You can check more of it out here.
Which leaves me with another interesting bit of trivia. What was Baden Powell's self-coined nickname in school? It rhymed with his name :D
Ans: Bathing Towel :)
