We are all born with our own tastebuds and, in this case, food environment. Some people can eat these 'top' Scoville winners BUT I am CONVINCED that the only reason that the 'Carolina Reaper' exists is for those Southern Boys to say; "Here, hold my beer and watch this!"
Me? I draw the line at Habaneros, I grew up on South Texas meals! Beyond that and I am DEAD!
