Ahhh memories... I was in Scotland over the winter when the heating finally gave up. We had a month where there was no heating AT ALL and it was snowing at the time. (Add that to the fact my window COULD NOT shut properly).
Anyway my Computer splendily did keep my room above freezing and I have it to thank for keeping me alive.
Now we have moved, (Same city) my room keeps over heating thanks to my computer.... you just can't win can you?
