A madcap Japanese great-grandmother armed with a camera and an appetite for mischief has shot to fame for taking side-splitting selfies. Many of Kimiko Nishimoto’s photos appear to put her in harm's way, but the great-grandmother says she has never injured herself. She took up photography at the age of 72 and has amassed more than 41,000 followers in just two months since she started regularly posting her hilarious snaps on Instagram.
