TOO HIGH?!! ARE YOU KIDDING ME?

Ok, So I went to donate blood at my school blood drive and when the woman checked my pulse, she said it was too high. I just shook this off as me being nervous, so I waited for a little while and they checked it again. Same thing. So they had another nurse come and check my pulse, no change whatsoever! That is when they told me that I couldn't donate. Yeah that REALLY made me happy. Today was the second time I had attempted to donate and the first time I grabbed the wrong paper for parental consent. This time I made sure that I picked up the correct paper. That didn't make me mad at all, but when your pulse has to be below 100 BPM and yours is only 112, WHAT IN THE NAME OF GOD IS THE DIFFERENCE AND WHAT COULD GO WRONG?!!!!!!!!? If you ask me they need to put on the information sheet they give you, that you will not be able to donate IF your pulse rate is over 100, even if this is normal. In my opinion if you have a pulse rate that is below 90 bpm, YOU MIGHT AS WELL BE DEAD! Even if you don't have any stress in your life, you should freaking be a dead corpse!!! I DON'T CARE WHO YOU ARE!
