From the moment we realize that we can keep and store memories, we start. There are many, many mini brain scrapbooks inside each of our heads. When we are young, there seem to be an infinite amount of hard drive space that we have only to remember to. As we get older, we find this to be a cruel untruth of life. Not everything gets saved.
Now with modern technology, every meal, ever monument, every moment can be recorded and shared. We have no issue asking a complete stranger to take a photo of us, to remember the occasion. It cements us to a time and date. Concrete proof of a moment of time, that we will never have again. There is a reason that most of think, if there was a fire at our home, most of us would grab the hard drives with all these Moments we have made. We really are a sappy people, and there is nothing wrong with that, nothing at all...
