Changed years to update dynamically

You don't need a 17kb (nor 82kb) dependency for this.

function age (since) {
  var diff = ((new Date()).getTime() - since.getTime()) / 864e5
  return Math.abs(Math.round(diff / 365.25))
}

document.getElementById("age").innerHTML = age(new Date('2008-02-08')) //> 10
