Science behind Indians eating food by hands

The hands are a major center for tactile sensations which are processed by the most advanced portion of the brain- the cortex. A more recent discovery is that tactile sensations also involve other portions of the brain to literally give us a 3D image of what we are touching. So its no wonder that Indians who eat with their hands insist the food tastes much better this way!. They are absolutely right. This is called mindful eating. So Indians who eat with their hands get a multidimensional experience of their food. We get more bang for our buck thanks to touching our food. We Indians get

• The sight of food
• The smell of food
• The texture/ temperature of food.

 Indian food is traditionally served in a thali like a palette of flavours and textures which we can combine in various combinations and permutations and get a different experience ever time.
However some common myths about why Indians eat with their hands should be discarded such as

Indians didn't have spoons?

Its certainly not for a lack of spoons. Indians used spoons gir religious rituals everyday and we had very cool looking spoons  to boot.

Indians were poor to afford utensils?

Even wealthy and middle class Indians eat with their hands, so its not because of poverty.

Indians were unaware of different cultures?

Indians were well travelled from ancient times with traders trading goods as far off as Egypt, Rome and China so they knew how non ndians used to eat food with utensils. 

So one can assume it was a deliberate decision, a well thought out decision.
