World’s oldest man aged 121 claims to be born in 1901 with documents to prove it as his family reveal key to long life

AFTER 121 years of living on this planet, the world's oldest man's secrets to longevity have been revealed.

Footage has surfaced of Andrelino Vieira da Silva undertaking his favourite tasks, with one of his granddaughters listing his top tips for a long life.

The video showed ancient Andrelino methodically adding ingredients to a lunch he was preparing for himself.

In the clip, the man looked healthier than ever, smiling and running viewers through his daily life.

The footage went viral and subsequently his granddaughter, Janaína de Souza Lemes, shared the centenarian's advice.

She told the G1 news portal: "He is lucid, active, cooks his food, takes care of his little things... He leads a normal life.

"He loves forro (a style of music and dance from north-eastern Brazil) and always goes dancing."

The Brazilian man has enjoyed stardom after defying logic with his astonishing age.

According to Janaina, many youngsters hail the man at any opportunity for a selfie.

Earlier in February, The Sun reported how the old man claimed he survived Covid after celebrating his 121st birthday.

Mr da Silva alleged he was born in 1901, the year Queen Victoria died, and insisted he has the documents to prove it.

He lives in the western province of Aparecida de Goiania and marked the supposed record landmark with a cake.

The cake was decorated with his first name, his alleged age, and the phrase 'O terror do INSS' ('The terror of the INSS').

The peculiar cake is a reference to the National Institute of Social Security which deals with pension payments and death benefits.

Andrelino is believed to have been married and had seven children, five of whom are still alive.

Mr da Silva also claims to have 13 grandchildren, 16 great-grandchildren, and a great-great-grandchild.

It is not clear if Andrelino and his family seek to have his age officially verified.
