A Tamil (South Indian) Brahmin (priest class) student of the University of Madras, with his hair tied to a nail in the wall, to prevent him from falling asleep in this photograph taken circa 1948.

2. Sit in front of a table.
3. No heavy meals.
4. Don’t use a table fan.
5. Drink more water.
6. Move around in your room.
7. Read out aloud while studying.
