Seems like it's easy to forget what day it is sometimes these days, and it's something that people of all ages are experiencing, so it's not just an older person's condition. Sometimes I wonder if this is occurring more because of environmental changes or because the human mind is just evolving to a different or advanced level of comprehension so quickly that it can't keep up with current days as well anymore. It may not be that serious or deep, but that's just one theory.
