As writer said, it is true that aggressive behavior or harassment on social media are increasing, however I believe it is wrong that increase aggressive on the Internet suggest we are more aggressive at our core. Rather, we can cooperate if we use social media effectively.  I think there are many people who want confront bullying or abuse, although it is difficult in the real world because everyone concerned about how they are perceived by others. On the internet, we don’t have to confront face-to-face so more people tend to act the way they wa...

Quick accounting reduces the burden on people.    Second, it is hygienic. Bills and coins are reused, so countless people are touching it. There may be fungus on it. It's very unsanitary.    However, in my opinion, it takes long time to become cashless...
