I just love yoga, I chose to do it once a week on Tuesdays.
According to most calendars, that's the 3rd day of the week, with the week starting on Sunday.  But I think many of us see it as the 2nd day of the week.
I think so too, nowadays week usually starts on Monday. And Yoga is so relaxing, perfect for beginning of the week.
It seems that yoga originated in ancient India - do you practice a certain type?
I like Bikram yoga myself. I think there is many different kinds. I heard of Ashtanga yoga as well.
Do you do the Bikram yoga where they add the heat and humidity and is then known as hot yoga?
Yeah that's what I like about it. 
I'm not so sure I'd like that - exercise under hot and humid conditions - sounds like a good way to make myself pass out - LOL!
You do need a lot of endurance to do it, but if you like exercising it's perfect for you. I like yoga because different poses challenge my body.
Yoga Yajnavalkya
The Yoga Yajnavalkya (, "Yoga-Yājñavalkya") is a classical Hindu yoga text in the Sanskrit language. The text is written in the form of a male-female dialogue between the sage Yajnavalkya and Gargi. The text consists of 12 chapters and contains 504 verses.
Like Patanjali's "Yogasutras", the "Yoga Yajnavalkya" describes the eight components of yoga; however, it has different goals. The text contains additional material that is not found in "Yogasutras", such as the
in Los Angeles but achieved little attention elsewhere. "Nowadays Clancy Can't Even Sing" was listed at number 110 on the "Billboard" charts on August 20 before disappearing just a week later. On the single's lackluster commercial performance, Furay later suggested "Nowadays Clancy Can't Even Sing" was "too deep" and "too ambitious" of a choice for the A-side, and considered "Do I Have to Come Right Out and Say It" and "Sit Down I Think I Love You"
