Good Agile, Bad Agile

I just finished reading Steve Y's Good Agile, Bad Agile. I think this anecdote was my favourite part:

Most engineers are not early risers. I know a team that has to come in for an 8:00am meeting at least once (maybe several times) a week. Then they sit like zombies in front of their email until lunch. Then they go home and take a nap. Then they come in at night and work, but they're bleary-eyed and look perpetually exhausted. When I talk to them, they're usually cheery enough, but they usually don't finish their sentences.
