Nanatsu no Taizai wikia says Ban is at least 1103 years chronologically.
But in season 2 of the anime, his adoptive father when they re-meet tells him he looks 20 for someone who should be 40. Also, in the wikia, his adoptive father age is 65, and his adoptive father knew him before he was inmortal and told him how to gain inmortality from a story he thought it was a fairy tail. So how old is Ban? Is he 40 or is he 1103 years old?
