scared of losing a tooth, f*ck yes i am!
Lower face pro steams up my glasses, so i often leave it in my backpack.. but then i take a bb close to the mouth and pull it out again, then i get fog and they go back in the bag, then....
well you got it, i hope.. on the other hand i'm experimenting with various homemade solutions
Other than that, no, not scared of anything..
