On my opinion, unusual it's something that seems surprisingly.
Anything special , thats could give us any feelings,such as happines,angry or sadness.
For example,yesterday my classmate give me chocolate bar,it's was unusal and after that I feel happy and satisfed,because of understand that I have nice friend,at all! This example can give you elementary imagery about what means "unusual"...
As I know , resesarchers explained thats only another way to school,work or home can improve your memory and imagination.So little unusual things,it can be something easy,but necesarry, are important part of our life
