I voted 'other'
I usually shut down at night - although when 'night' comes, can be variable
During the week I start up to check mail & BBC news in the morning, then shut down when I go to work - and start back up, when I get home.
At weekends if I start up during the day, I will usually leave it going, even if I go down town, or anything - but that is more laziness, than anything else
