So i just figured out the other day that i am immune to bee venom. The other day i was driving to home from work and a bee flew into my car, i swatted, it stung me in the arm, then left out the window at about 75mph. It hurt a little bit but it was more like itching than stinging or throbbing. So i get home to see this massive red bump about the size of a dime already formed around the sting. In the center was a small black dot, the stinger, which i carefully removed with my Jegs digital read-out micrometer... i couldnt find tweezers.
About 20min later i looked at it again and it seemed to have a small yellowing dot forming abournd where the stinger was. It didnt hurt to touch and even press on. So curious to see if what was forming would come out, i kinda squeezed on the sting bump. Low and behold, a small small drop of yellowish translucent fluid seeped out which i took to be the venom form the sting. 30min later, the bump was gone and i had only but a small red dot on my arm like i had been pricked with a clothes pin.
So in 1 hours time, i had gotten stung, swelled up, my body appearently told the venom to fuck off, and the swelling had gone away. So in closing, the bee died while i only lost 1hp for about an hour.
