I am confident your colleague works 5x harder because he/she does not want to get the spelling of century wrong. This is not a simple typo.
For me, these mistakes are equivalent to Van Halen’s “Brown M&Ms” (see trending HN article: https://news.ycombinator.com/item?id=23985817), and I stand by my original assertion.
