In many ways it's much harder to be a human than it is to be an animal, and when you add the human knack for overthinking everything into the mix it becomes nearly unbearable to be human.
We build stuff that other people will inevitably want to tear down, we make ourselves look appealing to others only to be rejected, and we fight for survival only to be run down in the street.
Japanese artist Tetsuya Ishida knew the pain of being human all too well, and his surreal paintings reflect his feelings of isolation, dissatisfaction with society and the harsh reality of his life in Japan.
Ishida died in 2005 after being hit by a train, and it's unclear whether he committed suicide or was the victim of a horrible accident, but whether Ishida was depressed or not the paintings he created are miserable masterpieces.
