Joshua Foer: Using Memory to Prolong Your (Perceived) Life

"Monotony collapses time. Novelty unfolds it," reads Joshua Foer from his book, Moonwalking With Einstein: The Art and Science of Remembering Everything, explaining that creating more worthwhile memories can lengthen our perception of time.

In summary, if you create new "exciting" memories more often the your life will seem longer. For example, go try something new or visit a new place (locally or far away). Although, the more mundane your life the shorter it will be perceived by yourself.
