With the invention of computers

With the invention of computers, internet and lately the social media, the communication around the world has increased and people living in different parts of the world connect closer when compared to our ancestors. Areas such as Art, food, Culture, law, and currency from different parts of world have integrated the recent years. Some people are also coming with idea of one world, one currency.Have you ever imagined a world using same currency, with one regulatory board? Well, this passed though my mind when I was traveling to Vietnam. Remembering the memorable days, it also reminds me the Hassel of exchanging the money into dollars and then into Vietnamisam Dongs.
