Answer 1: The author doesn’t feel like doing either one of them.
Answer 2: Google searches for both of them plummet as Christmas draws near, then spike back up after a new year begins.  Observe:

Relative frequency of Google searches for "Jobs" as a function of time

Relative frequency of Google searches for "Healthy Eating" as a function of time

Vertical gray lines represent new years.

I believe we’re seeing two very different holiday effects.  Around Christmas time, people are more reluctant to fire employees (retail businesses also experience their busiest and best time of year, which means they need and can afford more help).  Seasonal retail and holiday-related jobs, combined with a pent up demand for firing people (assuming employers are more reluctant to sack people during the holiday season), could explain the spikes after the dips.  This first holiday effect is fairly market driven, i.e., there are fewer people looking for jobs on the internet.

I’d guess that the second holiday effect would be almost entirely created by the people performing the searches.  Individuals load up on Christmas cookies, latkes, and big holiday dinners right before another group of individuals (perhaps with significant overlap) makes a series of Resolutions, in honor of the new year, many of which involve eating more healthfully (and turning to Google for advice on how to do it).

Both “holiday effects” seems to involve a combination of economic and social forces.  In addition to these two patterns being a great example of how correlation doesn’t always imply causality, are there any other interesting holiday effects out there?  And can we infer anything from the unusually low, though still pattern-fitting, results for “healthy eating”?  Is healthy eating being put on the back burner during an economic crisis?  And if so, what will the economic costs of that be in the future as we rescue and grow our economy with a less-healthy workforce?
