When the calendar flips over to January 1, we start to make promises to ourselves. This year, we'll lose weight. We'll be more organized. We'll spend more time with our families. But why is this the time for resolutions?
The Roman god Janus had two heads -- one that looked forward into the future and one that looked into the past. And while many Roman rulers made a land grab for the months of the year -- see August, October and July -- Janus stood strong at the beginning of the year. This is January. And on the first day of January, we look back at the year past and then ahead at the year to come.
