When you go to a butcher, the meat you buy contains muscles. Allah has created muscles of millions of fibers each of which ends in a nerve.
Whenever orders come to these fibers from the nervous system, they contract and become 60% shorter than they usually are. In other words, a muscle fiber whose ordinary length is 10 cm becomes only 4 cm long when it contracts.

This is simply how we move. You might be sitting in the living room, for example, and suddenly you notice that your little son is going directly towards the stove, so you jump forward to hold him back.
This means that in a single instant, you conceive danger and, therefore, an order goes, quite suddenly and quickly, from your brain to the muscles, which, in turn move and help you jump to him and take him away from danger.
This is an amazingly complicated process that depends on neural, chemical, and physical functions that all occur within a portion of a second.Pages: 1 2
