My occupation is teaching yoga. I teach in a yoga school and practice Buddhism.
Nice, I'd like to start doing yoga. What kinds of yoga are there?
We teach mental, physical, and spiritual yoga.
The history of yoga interests me, too. But I don't know much about it. 
Well it originated in India.
I see. Were there famous historic figures who are known for being great teachers of yoga?
I'm not sure, but yoga gurus from India brought it to the west in the late 19th century.
