I guess your very special job here on the Steem is to amaze me again and again..

😀 amaze is my middle name.

Learning sign language takes time and it work best with keen interest. Once you have develop a strong interest on it, you can achieve it.

I can even use it to sing song..., but would only be understood by deaf and dump or someone who also understands the language.

There are also other sign language based on the main language of the environment, but what I learn was mainly American sign language which is understood by almost all the English speaking regions in the world.

By the way, there is also a monetary need for this... Online. Signing podcasts. You may have already seen this on YouTube...

I have never thought of creating podcast with it, but I think it would be a good stuff to give a try.

Respect, my dear!
