Why Yoga? Why this Medium?

I am writing a paper for my English class and I want real world answers! My project is a series essays about yoga! I thought real expert testimonies would be helpful! I have been practicing myself for about three years but would like others opinions.

What do you find satisfying/rewarding about practicing and teaching yoga?
Why yoga? Why this medium, what is important to think or know about yoga?
Any specific people whom inspired you to do yoga; famous or not. (Can be multiple people)
Anything else you want to add would be much appreciated and feel free to expand on any questions you’d like!.
