It was never explained why Tanjiro managed to live past the age of 25. The most likely reason is the fact that the Curse has never been proven to exist. The Curse of the Demon Slayer Mark supposes that anyone who activates it will die at the age of 25 because the price of activating it is a person's lifespan.
Chapter 205 of Demon Slayer features a timeskip and mentions the death of Tanjiro three generations after the battle against Muzan. To sum things up, Tanjiro died fighting Muzan and was revived within seconds due to the transfer of blood from the Demon King to Tanjiro.

Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship.

Muzan is well over 1000 years old. Despite achieving an age that no one else has, his appearance makes him look like an adult man in his early to mid-30s. To get that look, Muzan drinks medicine that not only protects him from illness but keeps him looking young.
