Maybe the reason we call fingers digits is that we use them to count.
Why do we have raw data, or numbers? Are they healthier than cooked data? Or can you get an infection if you eat numbers that aren't cooked enough? If you cook numbers and put them in a book, you've cooked the books, which is illegal. My favourite number to eat would be Pi, but I would eat it raw. It's an infinite number and would take a very long time to cook properly.
