Most of the dev team works a very flexible 40 hrs. Some of the more senior folks work a bit more but its all because we want to. It would likely have been too much if we were pulling 60 hr work weeks.

We also travel extensively for our work anyway -- projects in Africa, India, Latin America -- so we're used to setting up shop pretty much anywhere. And definitely in less hospitable circumstances than Sao Paulo. So that helped mitigate the culture shock factor somewhat.
