Day 17 - Technology

My head hurts. Has done for the last 5 hours. I've run out of oomph to keep a relaxed festive vibe going in the house (yep, it takes lots of effort to keep it relaxed in our house) and am horizontal in front of the telly wishing I was asleep.
They're transmitting the Strictly final in 3D tonight. Don't really get the need for 3D tv. Sounds like the kind of thing that would give you a headache.
