As the birds wake up the people on the farm early in the morning, one man is already up. In fact, he has never slept not once in the past 36 years.

    The man has never been ill after so many years of insomnia(失眠). This has not only made him famous, but also interested many scientists to study him.

    Sixty-four-year-old Thai Ngoc said he could not sleep at night after getting a fever in 1973, and since that time he has experienced more than 14，000 sleepless nights.

  “I don't know whether the insomnia has impacted my health or not, but I'm still healthy and can work normally like others,” Ngocsaid.

His wife said,“My husband used to sleep well, but these years, nothing can make him get to sleep.” She said when Ngoc went to Da Nang for a medical examination, doctors said he was healthy.

    Ngoc now lives on his farm at the foot of mountain, busy farming and taking care of pigs and chickens all day. “I have tried sleeping pills and some other medicine, but nothing helps,  even to sleep for a few minutes,” he said.

    Ngoc often does more farm work or helps his neighbors during the sleepless night.

    Angelo Casimiro made something new at the age of fifteen.

    Casimiro made a device(装置）. It can charge（给……充电）your cellphone as you walk! When you run, jump or walk, a pair of discs(唱片）inside the shoes can produce electricity. It can be used to charge your phone or any other devices with a USB port!

    People have to move a lot if they use the device to charge. Those who like travelling in the wild will love it. It takes about eight hours' jogging to charge a lithium-ion（锂离子）battery and two hours' playing basketball will only give the cellphone about 10 minutes' charge.

    A device called SolePower is a kind of insole（鞋垫）that can produce electricity. SolePower is like Casimiro's device, but it can fully charge a cellphone after over a four-kilometre walk. So there's a lot for Casimiro to do to make his invention（发明）better.

    Anyway, Casimiro's device is quite good. After all, his invention started something new, right?
