I missed that bit which you added on. Doesn't sound so life threatening now.

The answer to the revised question is quite straightforward, in that it passes a rather long day at work, sitting on my arse doing nothing, save picking up the occasional book or cup of tea. I have to be here, as progress demands it. There are no hunter gatherers living in Berkshire, and i have to pay my taxes, for all that hospital treatment which will hopefully one day save my life.

I don't like to feel as though time is really 'wasted'. That makes for quite a depressing atmosphere, and merely serves to promote regret and stir hopes for more time. Of course, if there is a project to complete, with an implausibly tight deadline, then there will always be the shadow of wasted time........
