Beetel Nut Paatti
It's a common practice to chew Betel nut and Betel Leaves in India after a meal. It helps in digestion, acts as a stimulant and also is an effective source of calcium. Old people in India cannot chew the betel nut since its very hard and old people tend to loose tooth by the time they are 70 years old. Hence they use a small device like the one you see in her hands. Its called a "Ammi" in tamil meaning grinder. The Hard Betel Nut is placed in the center of the "ammi" and is powdered with a "koshavi", the iron or stone made hammer. Usually the device is made of Iron or can even be made if stone.
This old lady was grinding her betel nut when me and mamen visited her house. Mamen of course not having seen this was so excited by the scene. The women around this old granny were shouting at her to grind the betel nut harder since mamen was taking pictures. I believe the old lady was hard of hearing and did not really notice or oblige to the screaming women around her.
