Food Poisoning

How does it happen?, where does it come from?, how does it start?, where is it found most commonly?, what are the side effects?.... We all know the asnwer to the last one. My friend Simar got food poisoning the other day and was tested for Ecoli, which is a more serious case of food poisoning that can sometimes lead to death. Thankfully he did not have Ecoli and just had common food poisoning. I have never gotten it so i cant really speak from experience but it really sucks. God its just non stop puking or shitting, until it decides it truly 100% out of your body. We think he got it from a chicken and rice stand that we always go to in Manhattan but my other firnds ate the same exact thing and did not have anything happen to them not even a stomach ache. I just hope i never have to deal with what he went through because its really shitty....literally.
