     It is probably the strangest sport anyone has ever invented.And at first sight,it looks like the easiest.

Competitors have to do two things.The first is to stand still.The second is to place their hands anywhere

on the body of a car,and keep it there.

     This is where things start getting difficult.Lots of people are doing the same thing.And the winner of

the "handathon" contest is the person who can carry on doing it for the longest time.That person gets to

own the car.

     It still seems to be an easy thing to do.At the beginning it is.Anyone can stand still.But when the

contest has been going for four or five days,standing still seems like the most difficult job in the world.

And keeping the hand in place over this time becomes an act of serious attention.After a few days,the

hand seems to belong to someone else-someone who wants to go home and get some sleep.

     Competitors are allowed to take a five-minute break every hour to eat,drink or do whatever else is

necessary.No one is allowed to lean on the car for support.Winners need to be able to show great

powers of attention.They also need to be able to develop special skills.

     Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete

to enter.Entrants in the Longview handathon certainly don't seem to do much preparation.Most say they

will prepare by "getting lots of sleep".Others say they will "eat healthy food" or "pray for success".The

whole event gives ordinary people the chance to do something interesting and win something in the end.

     Handathons are competitions,but there is little rivalry (敌对) between competitors.They help each

other out and keep each other's spirits up.People who drop out early return with food,drink and

encouragement.
