I am spending 60 hours in front of a screen a week - at least. This is Monday to Saturday. I try to stay off screens all day Sunday but may end up doing a coupe of hours before I can ditch it (expect for the weather, taking photos and taking phone calls).
This 60 hours is not spent at my desk - where I stand. It is spent at my desk on a two screen iMac, on a sofa (or in bed) with a laptop, all of these places and out and about with an iPad and iPhone.
Yes, I work in the bath. Yes, I work in cafés. Yes, I might even dismay our dog by dealing with things on a park bench out somewhere.
But I get stuff done.
What I DO NOT MISS is time wasted commuting. It isn't just the time spent in the car, in traffic and getting parked (getting petrol), it is the time spent getting ready to go out > get washed, shaved and dressed (appropriately).
I am not fit. Damage to my knee on a walk a few months ago testifies to that. But I do eat healthily. Just two meals a day. Nor do I drink (or not for the last 11 weeks). I drink far too much coffee.
