There are several cultures around the world, that insist, that eating with our hands is better for our digestion, than using cutlery.
They say our fingers, release certain enzymes that not only aid digestion, but improve the flavour of our meal.
The key being to lick our fingers clean at the end also.
I can understand, that many wont feel comfortable doing this in a restaurant in public, as it is seen as 'primitive'.
But try it at home for a while, and see!
