So that leads to, if we could inject memories we could live more than a lifetime's worth. Or maybe accessing others' memories via stories, (reading, movies, etc.) adds to our store of memories and makes our lives richer. But this is assuming that having the most memories at the end is the goal of life. But your memories are also gone when you die. The only thing that remains after you die are memories in others' minds about you. The bigger your achievements the longer the memories about you will last in the collective mind. Maybe that's a better life goal.
