I think deleting the topic is not a great idea, for example because of Khemarato Bhikkhu very good answer, which is valuable, so it is worth preserving. 
. Thank you Bhante! 
I’ve allowed myself to change the name of topic from: “Abstaining from lying down: Anyone dance the Dhutanga?” to “Abstaining from lying down: anyone practiced this Dhutanga?”, to avoid any potential unpleasant associations with the name. Of course final dicision lies in hands and hearts of our dearest moderators.
