How to make yourself NOT cry

I do not know about the rest of you, but I have had many moments in the past when the tears came up at the worst time. I do not cry easily, but when I do - I hate it. There are things you can do to make yourself not cry.

• Clear your throat. That simple. When the tears bubble up, clear your throat. When you feel a strong emotion it translates to stress in the automatic nervous system. The ANS increases oxygen and sugar to the muscles, in order to do this the ANS triggers the body to get more oxygen to the glottis in the throat. The urge to cry is the larynx responding to this stress by widening the muscles in the throat to get more oxygen into the body. This is the point where we feel tightness in our chest. Some will hold their breath or stop breathing, and constrict this muscle in our throat. If you are about to tear up, just clear your throat and it will briefly interrupt this process.
  
• Swallow. Swallowing will lift your tongue to the roof of your mouth. This blocks the soft palate and makes you usable to cry.
  
• Look directly into a light. This will confuse the pupils and prevent the tears from flowing.
  
• Close your eyes and roll them. This will confuse the pupils much like looking right into the light.
  
  Before The Cry Comes On:
• When you feel a cry coming on, take a deep breath, hold it, then without exhaling  suck in more air, and hold it in for another five seconds. Take in another puff of air - do not exhale - puff in, in, in, in. Then, exhale and breathe normally. This trick immobilizes the diaphram. This technique focuses on your breathing, relaxes everything and gives you time to get your composure.
  
• When you feel a cry coming on, start swallowing and clearing your throat. It is better to start this before the cry starts than after.
