Aside from breathing, Bikram Yoga classes are quiet affairs with only the instructor’s guiding voice taking you through the 90 minutes. That said, three things are not real desirable to have happen, especially all in the same evening.
1. A sneeze
2. A Yawn
3. Your stomach remembering you skipped dinner so it makes its displeasure known by screaming like an stereotypical old man “oyoyoyoyOYOYOYOYOYOYoyoyyoyoy”
If you had any flow to your work, that last one takes it away.
