In Japan, the global leader in high-tech¹ toilet design, the latest restroom marvel² should come with a health warning for hypochondriacs -- it doubles as a medical lab that can really spoil your day.

作为高科技马桶设计方面的全球领先者，日本最新设计的一款马桶能为那些怀疑自己生病的人敲响健康警钟，不过这款兼有身体检查功能的马桶真的会让你郁闷一整天。

An employee of Japan's housing company Daiwa House demonstrates the company's latest model, called 'Intelligence Toilet', manufactured by Toto, at Daiwa House show room in Tokyo.

Japanese toilets have long and famously dominated the world of bathroom hygiene（卫生，保健） with their array of functions, from posterior（后部，臀部） shower jets to perfume bursts and noise-masking audio effects for the easily-embarrassed.

The latest "intelligent" model, manufactured by market leader Toto, goes a step further and isn't for the faint-hearted: it offers its users an instant health check-up every time they answer the call of nature（解手） .

Designed for the housing company Daiwa House with Japan's growing army of elderly in mind, it provides urine analysis, takes the user's blood pressure and body temperature, and measures their weight with a built-in floor scale.

"Our chairman had the idea when he was at a hospital and saw people waiting for health checks. He thought it would be better if they could do the health tests at home," says Akiho Suzuki, an architect（建筑师） at Daiwa House.

Toto's engineers developed a receptacle（容器） inside the basin to collect the urine for sugar content and temperature checks, and an armband to monitor blood pressure. The readout（示值读数） is displayed on a wall-mounted computer screen.

"With the current model, your data is sent automatically to your personal computer, and then you can email it to your doctor," said Suzuki.

"In the next generation model, the data will be sent automatically to family members or doctors via the Internet," she said.

The electronic marvel（奇迹） , called the "Intelligence Toilet", is capable of storing the data of up to five different people and retails³ for 350,000 to 500,000 yen⁴ (about 4,100 to 5,850 dollars) in Japan, she said.

"For now our customers are essentially⁵ middle-aged⁶ and senior people. But we hope the young generation will also become more health-conscious."

The model is the latest advance in a string of sophisticated toilets, known as "washlets" in Japan, which have become ubiquitous（到处存在的） in recent decades.
