Wow Cai, that is awesome

When I am working, I stand minimally - I catch the train to & from work (an hr travel each way) and I usually read a book so I find it easier to sit. I have just started getting off at Richmond and walking into work twice a week (30 min walk). I work in an office but do walk to the printer, photocopier/scanner, although most of the time I sit. At home, I am up a bit more except at night where I sit from about 7pm onwards....
