Brain Researchers Open Door to Editing Memory

The article's titled Brain Researchers Open Door to Editing Memory, pretty much is self explanatory. Let me start of by saying, who doesn't want some part of their memory to be gone forever. Everyone has something that has happened in their life, that has caused them to be different, scared, or upset over it and would love for it to have never happened. What if it really could? What if the scientist have came up with some sort of molecule that could erase that one memories like chronic fear, a traumatic loss, even a bad habit. To me, this all seems to good to be true. If you read the article it talks about how they have tested this only on animals such as rats. He states "He teaches them to move around a small chamber to avoid a mild electric shock to their feet. Once the animals learn, they do not forget. Placed back in the chamber a day later, even a month later, they quickly remember how to avoid the shock and do so." My question is, how is are brain even similar to a rats brain, this just doesn't seem right. Even though the mice and rats may of done exactly what they planned, who said a humans brain will act the same way. Many things could go wrong in this procedure, such as, what if you lost a memory that you didn't want to lose. Or say your bad habits are gone, but what if your curiosity about it increases and it becomes worse. To me a bad habit is all in your head any ways. Even if a drug could erase it, why would it come back. It just seems to me that scientist are coming up with different things that doesn't even really matter. We need to find many cures for other things, but then again, a man came up with the cure for cancer many years ago, and he suddenly disappeared. It's all about what the goverment thinks any way.
