Tonight, when you are in bed to sleep, count all English words which you know starting with "A". Your eyes can be open or closed; optional. Don't use any pen or paper (in bed!). The more words the better. Do this exercise until you would fall asleep.
Actually this exercise is very useful for people who have sleep problem in bed.
In the morning, you should remember how many words you counted last night.
In counting the words, you may use your fingers (optional).
Try to keep this exercise an every-night action if possible. One night for words starting with "A", next night for words starting with "B", ... In this way you are sure that your mind is a bit more maintained.
