The reasons for my not choosing the other product are as follows. For one thing, life should be a bowl of cherries. When we can predict everything before hand, life is not that intriguing. For another, I would like to savor all the occurrences in person instead of for seeing it. I will be moved by an unknown event, but I will feel bored with reasonable matters. Last but not least, I am a man of the spirit of adventure. I like to clear the hurdle in front of me, further catching a glimpse of what it is hided behind despite ferocious creatures or aliens. I worship the spirit of Hamlet to some extent. I even admire Faust in terms of his desire for knowing everything. With these models, I firmly believe that it is true to be adventurous. Hence, I merely need my own eyes rather than smart glasses. In a nutshell, smart glasses will cloud the vision of humans, while invisibility cloaks will create a kaleidoscopic world.
