Thanks Mark and Maria.

As I'm overweight by a few kilos, I'd be compromising my knees and ankles by standing for long hours. So, I wouldn't be going that way. :-/

I wonder if you could tell me of a way to sit without putting pressure on discs. Do you know of anybody who has tried a balance/stability disc?

A yogic way of sitting is called vajrasana. It works well for me at home but in the office? Another story or maybe a story a day! :-)
