how to use vectors to control an outcome

I need to find a game object and look through the object for the children finding their position subtracting vector A from vector B to find the points between each.

If vector A is above vector B then do this...

The points the vectors are attached to will constantly be moving as object is controlled using gestures

The code below is what I have written to find the children of the game object.

I would need to use the vectors to figure out the position of the children. To extend my example I would need: if the left hand is above left elbow then it should do this..

public class kinectman : MonoBehaviour{ public GameObject man;

GameObject lefthand; GameObject leftelbow; GameObject righthand; GameObject rightelbow;

void breakdown() {

  lefthand = GameObject.Find("13_Hand_Left");
  leftelbow = GameObject.Find("11_Elbow_Left");
  righthand = GameObject.Find("23_Hand_Right");
  rightelbow = GameObject.Find ("21_Elbow_Right");

}

Running 4 Find methods in a row is a horrible use of resources. $$anonymous$$ight I suggest finding objects in children? An example might be.

         GameObject[] parts = GetComponentsInChildren<GameObject>();
 
         for (int i = 0; i < parts.Length; i++)
         {
             if (parts[i].name == "13_Hand_Left")
             {
                 lefthand = GameObject.Find("13_Hand_Left");
             }
             else if (parts[i].name == "13_Hand_Right")
             {
                 righthand = GameObject.Find("13_Hand_Left");
             }
         }
         if (lefthand.transform.position.y > leftelbow.transform.position.y)
         {
             //do stuff
         }
