I've believed for a long time that forgetting details is pretty common when we get older. Sometimes I can remember more details about something that happened 30 years ago than something I did 30 days ago. Now new research out of the University of Toronto says that's perfectly fine.
Here's the science behind why forgetting is a sign our brain is working well. The study shows the growth of new neurons seems to promote forgetting. This happens so we can make room for more important memories and let go of the not so important ones.
Professor Blake Richards the author of the study says: "The point of memory is to make you an intelligent person who can make decisions given the circumstances, an important aspect of being able to do that is being able to forget some information."
So the next time you forget to pick up milk on the way home or the password for something it's just your brain waiting for more useful information. Works for me!
