I took my treadmill desk apart with some help from my dad, carried some pieces down three flights of stairs while my dad and a friend on mine carried the other pieces and the actual treadmill, carried back pieces of a regular desk (chair included) and two bookshelves while the aforementioned friend and father carried the rest, and after my friend was done assembling the new desk and I was done testing the chair for comfort, we went to play a bunch of boardgames.

(It might not sound like much, but I do believe I did my share of work. There were a lot of pieces,  and heavy ones too.)

My plans for the rest of the week are: put the bookshelves back together again and reorganize my office. I have too many piles of stuff everywhere; it will do a world of good.
