Spring asks a lot at once: longer days, fuller calendars, the clocks moving forward in March. A few small resets keep it from running you.

There is a reason a warm shower feels so good on a stiff neck. Warmth tends to relax the muscle it rests on: warm tissue stretches more easily, and blood flow to the area picks up.

January brings a push to do things differently. By February the push tends to fade and the calendar fills back up, so the habits that last are the ones already on it.

Many resolutions fade by February because they are too big, too vague or never given a time. The ones that last pass three tests.
