I say thats not science. Based on my own experience ive met people with sharp k9 teeth and some with flat. Ive taken mental note through my own experience thay people with the flat k9 teeth typically dont enjoy eating meet in the first place. As someone who has sharp ones as soon as I start getting better from being sick I crave red meat badly. Just an observation. Dont know about this synthtic stuff. Imitation crab meat is good but doesny satisfy the spot.
