Question

What would happen if we stopped shaking hands

Answer 1

Answer:

If we stopped shaking hands there may be, for an older generation, a sign of a lack of respect (though that can be shown in other ways).

Explanation:

Shaking hands is used as a form of greeting, expressing gratitude, and even used to complete business or diplomatic agreements.  So, it does play an important role is society, but at the same time, I do believe that there are other ways of showing respect, a greeting, or completing agreements.
