So, the philosophy prof lines up an engineer and a mathematician, both males (sorry, ladies) at the start line. One hundred units away is a gorgeous female. The prof states that each time he blows the whistle, eash contestant may travel half the distance to the "finish line".

He blows the whistle and the engineer makes a mad dash to the 50 unit line while the mathematician laughs raucously.

The Prof asks the mathematician why he is laughing and not racing. He replies that if one travels half the distance to his destination at each whisltle, he will never reach the destination as the resultant separation is asymptotically infintely secure.

The prof explains this to the engineer and asks why he bothers to race so passionately. The engineer replies that he will eventually get close enough for all intents and purposes.

Like I said, I cannot provide anything to the discussion, but....
