Wikipedia:Avoid statements that will date quickly

Unless you are writing on pages that are regularly refactored, such as Current events, you should avoid statements that will date quickly. Phrases to avoid include "recently", "in modern times", "now considered", "is soon to become", and "the sixties"; instead use phrases such as "as of October 2001" or "the 1960s." In many cases, such statements are also more precise.

Imagine someone is reading your words in six months, five, ten, fifty years. Will they still make sense?
