79 year old Constance Ngubane spars in the ring as she takes part in a “Boxing Gogos” (Grannies) training session hosted by the A Team Gym in Cosmo City in Johannesburg on September 19, 2017. The grandmothers, many of whom are over 70 have been training with coach Claude Maphosa and claim that they no longer suffer from the ailments they had before, and are stronger than ever. The grannies travel from all over Cosmo City for the twice weekly sessions. Coach Maphosa is in the process of planning events in other areas for grannies who have been inspired by the story, to join in. (Photo by Gulshan Khan/AFP Photo)

Mohamed Badr al-Din (R) stands in front of his vintage cars along a street where he keeps them, in the al-Shaar neighborhood of Aleppo January 31, 2015. The 66-year-old collector nicknamed Abu Omar inherited the hobby from his father and has a large collection of vintage cars, some of which he says belonged to former Syrian officials and were used in several movies and shows. Before the unrest, Abu Omar planned to open a museum to display his cars, which are guarded from pedestrians by a turkey that he owns. He hopes that the turmoil in the country will end so that he can pursue his hobby and repair his cars, which are heavily damaged from shelling. (Photo by Abdalrhman Ismail/Reuters)
