Afghans and Turkish People Similarities

[serat94]

Is it just me or has anyone else also noticed that Afghans and Turkish people share a lot of cultural similarities such as kissing the hands of elderly people, pouring water when someone leaves on a journey, among a few others?. How did these two countries share such similarities when they are located far off each other and historically speaking, Ottomans never happened to occupy parts of Afghanistan.

I think those similarities are eminent between societies near or along the Silkroad and the Near East. Central Asian Turkic Peoples and Afghans have had considerable direct contact over the centuries, however, this is did not occur greatly with Anatolian Turks. Hence it seems more a product of Eastern Heritage through silkroad channels that may have even happened prior to Islam.
