Stale Fish

Fish have memory. Some species of fish have memory which lasts for about 8 seconds, but that is the maximum observed in the fish world.
8 seconds of memory. Which explains why fish keep making jerking movements every few moments. The poor guys have no clue where they were setting out to 8 seconds back. So the fishy looking jerkiness. 8 seconds of memory. After each 8 second gap they would remember nothing. Like a ram chip recording for 8 seconds and then erasing itself. Record, erase, rewind every 8 seconds.
As a result of the 8 second memory cap, many events in the fish world are governed completely by when exactly one was born.

To illustrate:
Small fish Guppy was born at 8.21.30 sec and Small fish Guppy the second, his younger sibling was born at 8.21.31 sec on September the 3rd 2003 in the east western swirls of the Indian Ocean. Now S.F.Guppy and S.F.Guppy the second, were blissfully unaware of the dangers of the waterworld [inspite of kevin costner] and were busy snacking on plankton [ plankton ofcourse, have no memory at all ] that surrounded their little water eddy.
A few miles northwest The Atka Mackerel clan celebrated the birth of Little Sharpy Jr. Since the atka mackarels were not sticklers for time they did not record the exact time of birth for Lil Sharpy Jr. The Atka mackarels were a violent tribe and they were tickled by the mere thought of crime, blood and all that fish, a la sea-slime.
It was a big day[sept 10 2003] at the Atka Mackarels, as Lil Sharpy Jr. set out South east to catch his first guppy dinner, all by himself. At exactly 2.20.06 secs Jr. settled down behind a large sea anemone to wait for some guppy to come by.
September 10th was a fateful day in the lives of the S.F.Guppy brothers. They had sworn to visit their old aunt who lived beyond the anemone fields. So they set out, one following the other, more or less efficiently as there was only a one second lag between their memories. [ Explanatory Notes: :)) Fish naturally know their blood relations and enemies by sight without assistance from their memories. A trait they no doubt picked up from the Italian mafiosi. Fish also have an innate ability to remember appointments with old aunts without assistance in the form of memory. This is a trait they picked up from the obscure fish movie 'Captain Correli's Mandolin' ( if you ask me why... er.... my 8 seconds are up, so i don't remember ) ]
The Guppy brothers, they were to deviate from their keep right route and turn left at the 3rd anemone junction to get to old auntie guppy's seaweed soup restaurant.
[Action:]

S.F.Guppy negotiates the left turn at exactly 2.22.38 secs.
S.F.Guppy the Second, fails to negotiate this turn at that exact moment because of the one second memory synchroniztion gap between him and his elder brother.
Little Sharpy Jr. grabs the moment and his dinner which kept coming right for too long.
One second too long. S.F.Guppy the Second was a second too late.
Little Sharpy Jr. had successfully quelled his own hunger.

8 seconds later:

-S.F.Guppy was saddened but forgot everything 8 seconds later. He then went on to his aunts -Seaweed soup restaurant and took up a career as a restaurant critic.
-Little Sharpy Jr. was hungry again.

Boredom and fishy methods to counter it:
Think of this one. You put a goldfish in a little fishbowl. This is what he goes through.
Start:
Oh! I'm a goldfish. In a small fish bowl. Thats nice.
In a very small fish bowl! Oh hell this place will run out of oxygen soon.
Oh No. HELP HELP Help Help i'm dyiiiii....8 seconds up.
And then again:
Oh! I'm a goldfish. In a small fish bowl. Thats nice.
In a very small fish bowl! Oh hell this place will run out of oxygen soon.
Oh No. HELP HELP Help Help i'm dyiiiii....

8 seconds up.
etc etc etc
So all you need to do is to aim to thnk like a fish and you will never be bored long enough for it to bother you.
Ok. Very bad. But I'm a fish.
