This is nicely written, @rayt2 but I do wonder where you got your facts from? Things like...

>Yoga works wonders for diabetic patients. In fact, practicing certain yoga postures is very useful for people with diabetes.

>Yoga can also cure high and low blood pressure and heart-related diseases.

>People are reducing stress by meditating with Bhujangasana, Markatasana, Bhramari Pranayama, and deep breathing, while others are keeping themselves fit by learning some special yoga postures for Surya Namaskar. 

... all sound very plausible, but I'm guessing you don't just know these things and had to look them up. Including your sources would be helpful in the future, especially when dealing with medically related topics like this.
