Too much XP bad for perspective?

I just finished a conversation with a good friend of mine on yahoo, back in London.

He is actually doing waterfall, the full thing, in all its glory! He is working 70 hours a week, and the consultants at the client site are doing the full power-point, ms-word, up-front, plan, design and schedule thing to the hilt.

"the hillarious thing is, we are so far behind schedule that none of the docs relate to the solution" he says.

Doing XP for years has been bad for my perspective. I'm not sure I could tolerate that kind of environment any longer.

Am I ruined as a consultant?
