Also I'd like to add to this statement as being entirely false, from just one of my own personal experiences. For instance, I had an allergic reaction from getting stung by a hive-full of bees. I'm not allergic to bees, so it didn't kill me but my body was definitely in a fight-or-flight situation. However, I didn't experience any of the reaction until approximately 3-4 hours later. Wherein the first initial signs of the reaction beginning, was around the time my arm-pits swelled up to the size of grape-fruits. Then from there, it just started getting out of hand (hospitalized), but again this was all three to four hours later!
