> Yoga has zero place at a serious busines
It's "business", and why? Are you paying your (say) coders to write code? Unlikely, otherwise you'd measure their productivity in lines-of-code written, which I hope you realize is a bad idea.
More likely you're paying your coders to solve problems. Is sitting in a chair always the best way to solve problems/think? Not necessarily. If physical activity (like yoga) is conducive to better thinking/problem solving, and the company has the resources (Google does) -- I don't see why not.
