Well, Google will auto-suggest things based on:
- stats about you (location, etc), figuring it is likely that you are searching for things similar to what is searched for by those you resemble
- general commonality of a specific phrase
Vague words are unlikely to ever yield a search you really intended ... Try typing in just "why ", "how ", or "is " (yes, space after each) ...
