The octogenarians join a host of achievers in the latest catalogue of extreme feats.
Betty Goedhart, 85, soared to the top of the list to become the oldest performing female flying trapeze artist.
Ms Goedhart, from California, proved it is never too late, having taken up classes aged 78.
Chef-turned-DJ Sumiko Iwamura, 83, offered sage advice after being named the oldest professional club DJ.
The restaurant owner from Tokyo, who spins the decks for crowds after finishing her shift as a cook, said: “Try something and don’t give up ... there are opportunities lying around every corner.”
Ms Iwamura, who could be forgiven for feeling too tired to take on her slot as DJ Sumirock after working all day, said: “Doing something totally different is energising.”
Canine companions also made their presence felt, skipping and jumping their way into the record books.
Feather and Geronimo surprised owner Samantha Valle, 31, from Maryland in the US, by showing off their unusual skills after she rescued them.

Tom Bagnall from Staffordshire created a jet-propelled go-kart which, reaching speeds of 112.29mph, is the world’s fastest.

This year’s book features a section dedicated to the so-called maker movement, recognising inventors and creators of such things as the biggest water pistol and toothpick sculptures.
