Katara is alive as of Avatar: The Legend of Korra. She is 85 years old and is said to be the world's greatest waterbender and healer. She is also the father of Tenzin and the grandmother of his children.

The reason Aang died so much younger than, for instance, Kyoshi, is because he was frozen in a block of ice for 100 years while in avatar state. The thing with the avatar state is that it drains a lot of power from the body and can therefore affect the lifespan.

Aang died at the biological age of 66, but in reality he was 166. That is not so much younger than Kyoshi. :-)
