I had a stroke in my lower left lip - more evidence that academia is killing me

a friend pointed out to me that lately, when I talk I move my left lower lip to the side in a weird way - as if it was detached from the rest of my lips - when she showed me what I looked like I was horrified because it looked like I was talking like I had a stroke!!! she said I only do it when I talk about academic stuff, like migration, citizenship, rights, border policy and etc. So now I thought i would try a test and take a picture of myself pursing my lips and I am HORRIFIED to see that left lower lip really does kinda sag on its own and doesn't purse with the rest of my lips - I look like I had a stroke? Academia is not only turning my teeth yellow, making my hair gray but now it also making me lose muscular control of my lips!!! Well you know that aphorism that it takes more muscles to frown than smile - well scientifically it's true - so maybe I have been frowning too much in grad school!!!! Do people with Phds frown more than non-Phd's - unequivocally YES and I can produce a study to prove it.
