LongeviQuest is saddened to report the passing of Huang Decheng. Huang Decheng (Traditional Chinese: 黃德成) was born in the Empire of Japan (now Taiwan) on 14 November 1913 (according to his ID card). He passed away in Sanhe Village, Shuishang Township, Chiayi County, Taiwan on 20 November 2023 at the age of 110 years, 6 days.

Though official records indicate 14 November 1913 as his birth date, Huang Decheng asserts to have been 2 years older. If the date of birth on the ID is correct, he was 110 years, 6 days old at the time of his passing. He explains this discrepancy by stating that his family waited to register him due to concerns about infant mortality.

Maria Lacasse was born in Chertsey, Lanaudière, Canada on 4 December 1913. Lacasse’s caretakers describe her as a joy to work with, always smiling and eager to help, despite the demanding nature of their job. They spend almost more time with her than with their own families. Lacasse surprisingly claims that her bad temper is actually the key to her long life. To live a long time, she says, you need to be “uncomfortable.”

LongeviQuest is pleased to announce the age validation of Alfonso María Rojas Perdomo at 110 years old. He is the first Colombian supercentenarian from the Department of Huila whose age has been validated. 

Alfonso was born on 31 May 1913 in Palermo, Huila, Colombia. 

His family was forced to relocate to the Vereda “La Primavera” in Santa Maria, Huila, to avoid the violent conflict between the liberal and conservative parties of the Colombian politics. There, he acquired rural land with his brother and focused on agricultural and livestock work.

LongeviQuest is pleased to announce the age validation of Aiko Ōkubo at 110 years old. She was a Japanese supercentenarian born on 28 January 1913 in Mito, Ibaraki Prefecture, Japan. 

In 1934, she was married to a technical civil engineering officer from the Ministry of Home Affairs (now the Home Ministry of Japan). She had four children with him. 

In 1938, the family travelled across the sea to live in Manchuria, Northeastern China, which was a puppet state of the Japanese empire. Aside from enduring extreme temperatures during winter, the family also had to endure too many hardships such as their 20 km walk to Dashiqiao. They even got bundled into a freight train going north wherein they jump off the train because they don’t know where they are going. After a long, perilous journey in China, the family managed to get into a boat bound for Japan. They arrived at Maizuru City, Kyoto Prefecture, in June 1946.

Aiko tried to return to her hometown in Mito but found it completely burned down. On the other hand, her husband’s family was safe and unharmed, and so he inherited his family’s construction business.

Aiko travelled around Japan to visit nursing homes and give talks about her experiences. She would also play her Nagoya harp for them. Aiko did this until she was 104 years old.  

Mrs. Ōkubo was proud that she was able to raise fine and well-rounded children despite the hardships that they had to go through in China. One became a university professor, the other became a doctor, and the third managed a private elderly care facility. 

 Mrs. Ōkubo passed away on 22 September 2023 in Mito City, Ibaraki Prefecture, Japan.

LongeviQuest is delighted to share that Klavdiya Gadyuchkina celebrated her claimed 114th birthday. She is a Russian supercentenarian validated by the European Supercentenarian Organisation. 

Klavdiya was born on 5 December 1910 (despite claiming it was 24 November 1909) in the village of Norskoye, Yaroslavl Oblast, Russia. Her validation type is classified as low-level classification so LongeviQuest is yet to acknowledge her age validation.

At the young age of 15, she started working at a spinning factory as an auxiliary worker. She then dedicated her career to this establishment by progressing into the roles of a spinner, assistant foreman, and production leader.

When asked about her secret for having a long life, she would say “You have to work and treat everyone kindly.”

Klavdiya is currently staying in Yaroslavl, Yaroslavl Oblast, Russia.
