What you are today is a function of all of your experiences, thoughts, and decisions that you have had in the past and throughout your life. The most formative experiences are still accessible to us through our memories, good and bad, which continue to shape us. What if you could just erase from your mind all of the bad things that ever happened to you? Would you do that? If you could eliminate all of your bad memories, what would that do to the rest of who you are?
Some researchers are trying to find a way to erase bad memories from the mind. Sharon Kirkey in the National Post has written an article on this effort entitled If you could erase the worst memory of your life, would you? Scientists are working on a pill for that.
