Oops, I think I'm guilty!
I love to break into song and dance around. In fact I have timed my puter to ping every 15 minutes so I can have a good stretch, sing an ocatve or two, and sip some water. In fact, I never sit down now, and work standing, just ready to break into a few routines from 42nd street, or swan lake. (Depends on my mood, and whether I'm wearing a skirt).
I don't slurp from a sports bottle though, I use a glass.
I also love the radio on LOUD when I'm doing repetitive stuff. That way I can hum without having to strain to hear it.
I also use speaker phone, a lot.
Actually now that I think about it, I do work from home a lot more now, and my colleagues seem happier too...
( some of them are very grumpy though, and never want to talk about their DIY disasters or their bunion operation like I do! JOKE, well, some of it is)
