One Japanese woman has proved that age really is just a number.
    Masako Wakamiya learned how to use a computer at the age of 60 and now, at 81-year-old, she has released an app that shows people how to properly display traditional dolls for Hinamatsuri. Not only is Wakamiya a developer, but she has a blog where she shares clips from her travels and also teaches people how Excel can be used to make digital art.
    Wakamiya spent 43 years of her life leading in a bank in Japan and only started using computers at the age of 60, reports RocketNews 24.
    However, she is showing others that not all elderly individuals are afraid of technology and refers to herself as an ICT missionary, which stands for “information” “communication” and “technology. ”
    Wakamiya bought her first computer at the age of 60 and joined an online computer club to become more familiar with the technology—but this was after she set up and connected the computer to the Web on her own.
    After learning more about computers, Wakamiya came up with an Excel art that fills the cells with different functions that create patterns that produce colorful works of art—and now she is designing her own apps.
    Although Wakamiya may break the stereotypes of most elderly individuals, a study does suggest that she is heading down the right path to avoid other health risks.
    A team at the Mayo Clinic in Arizona linked numerous activities with preserving brain power in the elderly—but logging on seems particularly effective.
    Questions 9 to 11 are based on the passage you have just heard.
    9. What is this passage mainly about?
    10. Why does Wakamiya call herself ICT missionary?
    11. What seems to be quite effective in keeping brain power in the elderly?
