Wisdom teeth out? Damn...I really am the old man around here haha!
I'm surprised to hear you say that you're bad at MMA betting. When you comment on fights and fighters here, you have good insight from what I've read.
But what you say about letting personal biases affect bets is true. I did it in the past, and I have to consciously recognize my fanboyism about certain guys to make sure it doesn't color my betting.
For example if the next fight is Tony vs Poirier, my heart is gonna hold out hope that Tony's fight vs Justin was a bad night, the extra weight cut hurt him, etc. When in reality, I think Tony's age is just catching up to him at the highest level of the game. He can still beat plenty of guys, but I think Dustin does what Justin did to him at this point.
