Toastmasters is for everyone! Once you have to speak, in any language, it is recommended to join a Toastmasters club near you. Mushtaque was a Teacher. As a Teacher, he was communicating to and with his students on a daily basis. He was quite comfortable in that environment. Now retired, no students, no classroom, no tests and evaluations, he found out rather quickly that he wasn't as sound a communicator as he thought.
He decided to join Winners Toastmasters and got his mojo back and then some. He acquired even more skills and honed what was already a foundation from the classroom.
Have a listen to Musthtaque's #MYWHY for being a member of Winners Toastmasters.
