A beloved grandpa could not hide his joy when he got to play in a playground for the very first time at the age of 90. Pedro Oliveira had never had the chance to play on a swing or a seesaw – but on July 25, that was all about to change when he attended a family member's birthday party. At a farm near Londrina, Parana, Brazil, Pedro asked his grandson, Ludson, if he could play in the nearby playground, too. There, Ludson pushed his grandfather on a swing and rode a seesaw with him - with Ludson's wife, Joeline, recording the 90-year-old's joyous reactions on video.
