Where's he been? No tellin'

Your unfaithful correspondent has been running a little, writing for money some, and generally neglecting this web log.

I won't try to catch up or recap, at least not now. For the moment, here's a snippet from Gretchen Reynolds, writing in Tara Parker-Pope's Well blog at New York Times online:

 "The interplay of exercise and music is fascinating and not fully understood, perhaps in part because, as a science, it edges into multiple disciplines, from physiology to biomechanics to neurology."

The article describes a study on the effects of listening to music on headphones while exercising, in which the same set of songs played at normal tempo (once) and at speeds of 10% faster and 10% slower than actual (without the subjects' being told).

As you might guess, the music had a positive effect on the performance parameters measured, but the effect was markedly different depending on the speed of the music.
