There have been many studies and stories where a traumatic event occurred and memories were lost. Art has been used to bridge the gap in our lost memories. The brain like a muscle has built in memory banks and when there is damage done the paths become mislead or blocked. What art aids with is tapping into the creativity in our minds allowing new methods and paths for memories discovered.
Keep your mind young and healthy, view the world in your own creative image. Look for new ways to solve a problem. Thinking outside the box is good at times it allows different perspectives.
