Ignoring the Catholic priest's assertion that yoga, tai chi, and reiki are "unsavoury activities" because who cares, i will highlight for you the part of this article i enjoyed.

And an integral part of being into yoga is telling everyone you meet how ah-mazing it is, and how it's not just about being able to touch your toes, it actually brings spiritual calm and makes you an all-round better person - certainly better than you, with your creaking, befouled starch-hips.

...

But probably - no, definitely - the most unsavoury aspect of yoga is the feet. Being in an overly hot room with someone's cheesy feet shoved in your face as they synchronise their spreadeagle makes you wonder how you ended up here.

This is why i do yoga at home. No stranger's cheesey feet or stinky bottom in my face or line of sight. Toe socks. *shudder*
