Memory Erasing without Drugs

Fascinating practical application of Memory erasing method just published in Nature with a video explaining it:
"The technique exploits the way that human brains store and recall memories. When a long-term memory is recalled, it goes through a brief period of vulnerability, after which it must be stored anew to be remembered again. While the memory is in its fragile state, it can be modified or disrupted."
Similar to the file stored in in the computer memory whenever you revise it and save again it becomes a new information and old one overwritten by latest one.
