Would you rather a 4 day work week of 10 hr per day or 5 day work week 8 hr a day?

I'm in the boat with DinerDave and cbelt... I've been working 5 10s my entire professional life. I work for myself, so the more I work, the more I earn. The only time this wasn't true was when I was doing chemo for 3 months... I took more time off during that 3 months than the rest of my life probably. I assume I'll do this until my youngest is in done with college (another 10 years), then I'll finally reduce my hours.
