Josias de Oliveira is a supercentenarian claimant from Brazil, who claims to have been born on 21 October 1911. If his age is true, he could be the oldest living man in the world. According to the Gerontology Wiki site, he was last confirmed alive a few days after his claimed 112th birthday in October 2023. However, he was confirmed alive privately to me on 03 January 2024. I also found a mention of him from a website from 18 January 2024, but I don't know how reliable this website is. Regardless, he has been confirmed alive on 2024. I also have 3 photos of him from 2024, but I'm not sure I'm allowed to share them here.
