The term mail means "post, letters," c. 1200, "a traveling bag, sack for keeping small articles of personal property," a sense now obsolete, from Old French male "wallet, bag, bundle," from Frankish *malha or some other Germanic source, from Proto-Germanic *malho- (source also of Old High German malaha "wallet, bag," Middle Dutch male "bag.")
What is in your traveling bag? What tools do you use to survive? Where is your pencil? Nowadays the phone is becoming the tool to survive. What happens if you do not have a phone? What happens if the network goes down? Can you survive with pencil and paper? Can you survive using your brain? Will your traveling bag have your ideas? Is your traveling bag your brain?
