After 43 years working in one of Japan's leading banks, 81-year-old Masako Wakamiya has launched an iPhone app called "Hinadan" that shows users how to stage traditional dolls for the Hinamatsuri festival. From a report on CNN Money: She says she felt compelled to do something after noticing a shortage of fun apps aimed at people her age. "We easily lose games when playing against young people, since our finger movements can't match their speed," Wakamiya told CNN. The retired banker asked a bunch of people to create games for seniors, but no one was interested. So she took matters into her own hands and achieved something many people half her age haven't done. "I wanted to create a fun app to get elderly people interested in smartphones," she said. "It took about half a year to develop." Wakamiya started using computers at age 60 when she was caring for her elderly mother and finding it difficult to get out and socialize with friends.
