to think if I am lying in bed thinking about work and solving work problems in my head, then

[chomalungma]

it should count as work and I can claim the time back

Which is why I am awake at 4am having spent an hour thinking about work and solving problems.

I don't think the boss will buy it though. Or they might try the same thing!

Hear, hear! There is small a part of my brain that is a definite workaholic and loves to be busy at night. Every other fibre of my being is not. We all hate that part of my brain.
