body: <p>Why isn't this code working? I'm trying to use the method to add up the properties and then assign the added up properties to its own value.  </p>
  
  <pre><code>function howLongILivedSomewhere(college, home1, home2) {
      this.birthHome = 18;
      this.college = college;
      this.home1 = home1;
      this.home2 = home2;
  
      this.calcYearsAlive = function() {
      return birthHome + college + home1 +home2;
      };
  
      this.yearsAlive = calcYearsAlive();
  }
  
  var me = new howLongILivedSomewhere(4, 2, 3);
  
  console.log(me);
