Ever since I was about 11 I've had this concern over losing memories. Some sob stole a journal from me that I'd kept for 3-5 years. (Theft was years ago and I still haven't fully gotten over it--at least they found a way to make a memory stick!) That was heartbreaking! Here's an article about Making a Vivid Memory
A study in the May 27 issue of Neuron confirms previous models of memory recall that found sensory-specific components of a memory are preserved in sensory-related areas of the brain. The hippocampus can draw on this stored sensory information to create vivid recall.
It's a short article with nothing of great interest except the link to KidsHealth referencing the The Nemours Foundation
