Why negative aging? Because web pages are indeed of highly variable quality. In human–computer interaction (HCI) research, it's extremely rare to get this strong a finding, and Liu and colleagues should be credited with discovering a major new insight. The researchers discovered that 99% of web pages have a negative aging effect. This makes sense when individual components vary in quality: poorly made components usually fail early, so anything that has been in service for a long time is likely to be particularly robust and will usually survive even longer. Here, the hazard function decreases for larger values of t.
