The loss of long-term memories from the past as the result of a brain injury, infection,
illness, etc is called retrograde amnesia.
This kind of amnesia makes a person who suffers this amnesia unable to remember long term memories of events before the amnesia. It usually does not affect their ability to learn and store new memories.
I think the answer is it prepares your body for necessary action because I learned something like anxiety and how it help you take action last year. I hope this helps you.
The answer would be introspection. It is then the examination of one's conscious thoughts as well as feelings. It relies on observation of a person's mental state yet spiritually it refers to examining one's soul.Hope this would be of help.
