You hear about this practice a lot on the internet and it is very familiar to english-speaking converts but this practice is not typical among for example greeks christians in greece, or even most russians I don't think but I'm less clear on that.

As such -- as you say -- changing positions is good for our body which helps us to be more physically comfortable in this magnificent machine. Happiness is God's desire for us, but It has given us the absolutely free will to choose happiness or its opposites.
