Supposing you collect pens for writing, and that you really like to write with each of your pens (more or less). Then, each new pen means you have proportionally less time to write with each one of your pens, since you must divide the total writing time you have by the number of pens you have. The more pens you have, the less time you have to write with each pen. Time might come when you have only a couple of seconds to write with each of your lovely pens in a week or in a month... Does this sound like an ideal for a pen lover? Has anyone come yet with a solution to this sort of riddle for pen lovers?
