Even though this is a digital world, our brains will grab our memories and hang on to them. Our great-greats will be able to see our own world, our goofy clothes, and places we have been. As the generations pass, we will appear on slides and our own "Super 8".
Remembering and being able to remember is the challenge. Wanting to remember may be good or bad. Or it would be memories that are hard copy, paper to be held in our own hands.
