I'd really like to try yoga! I don't know much about it though, so I'm doing some research. Have you ever taken a yoga class?
Oh yes, I have, but there is such a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism, I don't think I'd ever experience all it has to offer
I didn't know there were so many different types! Is there a particular style you prefer?
I prefer Hatha yoga, but there is also Raja yoga
I'll look into those, thanks. When was yoga invented? 
The origins of yoga have been origins of yoga have been speculated to date back to pre-Vedic Indian traditions, but they are not all to sure about that
Wow, it's amazing that it's been relevant for all that time! What else do you know about yoga?
Well, it only became popular in the Western world in the 1980s
Oh, I see. It's supposed to be really good exercise, do you think that's true?
Oh yes, but it  is more than physical exercise; it has a meditative and spiritual core.
