At thirty years old, I have been teaching yoga for a third of my life. In my corner of the world, it's almost like a clique. Everyone knows who's who, and what's more menacing is that everybody seems to know each other's business. Of course, there are pluses and minuses, but for the most part, it feels more like a popularity contest than a viable career.
My gym's recovery fitness options include a sauna, a cold plunge and a hot tub. The sauna easily gets the most play. Sometimes there are so many people in there that hopefuls are forced to wait outside, shivering in their swimwear. The cold plunge is also really popular, but on a rotational basis. People tend to pop in for two minutes or so, often monitoring their process via a clock on the wall, as if performing a plank, then swap out.
