When would you change a 2005 Ford Focus' cam belt?

Ford tells me that my 50,000-mile 2005 Focus 1.6TIVCT does not need the cam belt changing until 100,000 miles or 10 years. I have read the discussion but there seems to be conflicting advice. What would you do?
There aren't a lot of premature failures, but six years or 60,000 miles is a lot safer.
