People look sadder now, people look happier in the past

There was this article i read around one years ago that reported this Polish guy, he went into coma and was unconcious for 19years(its really miracle that he woke up). Before he went coma Poland was still a communist country but now he woke up in a democratic capitalist nation. Frankly speaking it must felt terrible and extremely difficult to adapt, its really like slping for 19years and you wake up knowing some of your relatives has passed away, seeing your parents looking so much older than you can recall, walking on a totally different road to the same home, its urbanisation i should say. Nevertheless, something i earned from this article was something he said, it roughly goes like this, "people now are always with a sulky face and with a cell phone always at their ears." This sounds like a rather truthful statement because how often can you exclude a person 19years from world and bring him back to observe the difference. Therefore this thought of modern people looking sadder, feeling more unhappy struck me. But why?aren't you richer than your grandmother's generation, aren't you healthier than 曹操？Is development taking place at the expense of our happiness? To a large extent i really does feel so. The competition we are put in are so tough, nevermind if we're forced or willing to to earn more. You have to compete more in terms of mentally. there are so many things in your mind compared to just 衣食住行(food clothes shelter transport) in the oldern days. You fear, fear of terrorist attack, fear of nuclear missile, fear of retrenchment, you fear everything. Your mind just keeps working because you just cannot stay at rest, and time after time as the mind gets wear out, you feel unhappy, stress, tired and in the worse case, go mad.How sad is it:(Is it possible to just lead a simple life that we just demand for our basic daily necessities?i doubt so, we're developed and aim to grow more, nobody will wants to demote in this competitive World.How often can we see fun and loving music videos like the above one now?We are surrounded by sex,drug,violence,melancholy genre of media, its just so negative!
