Happy new year everyone! A lot can happen in one year -- or even in just one hour, or minute, or second. With each second that ticks by, 4 babies are born, 2 people die, and Earth travels 18 1/2 miles through space. 60 sets of this happen every minute, and then 60 sets of that every hour, and then 24 hour-long sets every day...that gives us more than 31 million seconds in a year. Let's see how much happens to us this year!
