Normally, I have been born with weird tastebuds as well: I liked coffee and everything bitter as a child, liked beer from the very first sip (although that could be due to being german) and had no problems with bitter vegetables as a child. Bit licorice was never my thing. Guess I have to try again after this video!
You think your tastebuds are picking up completely different tastes instead of just liking the bitter? That's really fascinating - I wish I was a food scientist and could study this :p
