Interesting stuff - and specifically, the numbers recommended are interesting. I've heard a 4-hour work day recommended in a few places.
Personally, I tried working 4 hours a day some years ago, whilst dealing with a death in the family. I was startled at how close to my usual 8+hour workday my productivity was - indeed, I'm not sure, looking at output alone, you could have told my 4-hour period apart from my usual work cycle.
I'll be interested to hear if anyone tries this 90-minute cycle specifically, and how it works out for them!
