     Ever felt like destroying the car in front of you when you're

stuck in an endless traffic jam?

     Well ,the Spanish company StopStress is offering clients(客户 )

the possibility of doing just that-but in controlled ,safe conditions.

     Clients can also destroy computers, mobile phones and TV sets

in what the company calls" destructible therapy" ( therapy : treatment

of a medical disorder).

     "We target the machines that cause the most stress in modern

life,"company co-founder Jorge Arribas said in a telephone inter-

view. "People get rid of stress by screaming and beating the ma-

chines until they are tired out. "he explained.

     The company, based in the northern Spanish city of Soria, uses

deserted cars that still work. Heavy-metal music is used to excite

the clients. They are given protective suits and glasses, helmets and

huge hammers.

     Most people's rage only lasts for 5 to 10 minutes. But some go

on for hours : they beat cars on which they've put the names of people

or ideas they would like to get rid of.

     "Some even get together to turn the car over, "Arribas says. A

session costs 60 euros(US $80)per person.

     Arribas says the idea came to him when he was having trouble

parking his car.

     "Dozens of people have used the therapy, which helps people

become aware of their stress level and helps them to slow down,"

Arribas explained.

     "It's better to channel violence in a controlled way than to get

it out on one's husband and wife or in a traffic jam. "he added.

     StopStress already has branches in three Spanish cities, and is

planning to extend its market beyond Spain's borders.
