@SayWhat1918. You have to have the right DNA and genetic code to posess that ability. So maybe if there are air nomads that can't bend but have the right DNA, the probably can learn airbending. Tenzin was able to teach his kids because they had the right genetic code, descendants of Avatar Aang. And Korra obviously because she's the Avatar. She has to learn Airbending. " it is not optional" - Tenzin.
