Question
Sometime when I’m studying at night, I become very tired,
but still I must go on studying because of upcoming exams. What should I do?
Answer
If you have no choice but to keep studying, then splash cold
water in your eyes some twelve to fifteen times. That will keep you awake for a
while. If you become sleepy again, then stand up and continue studying while
walking back and forth in the room.
