How Does Artwork on Walls Enrich Our Lives?

Walls are our life. We are surrounded by walls. Be it our home or office. We are surrounded by walls these days. With the growing length and gray of the walls, do you not feel suffocated? Your escape is either heading to the woods (very costly and also for a particular time) or to hang a beautiful painting. It gives you an escape, it only refreshes your brain after it is overloaded by files and work and an 8 GB ram which is almost full. With the boss yelling at you and your peers busy, how about a little zoning out through the painting?
