@Burton Langille Thank teacher, i remember that you said that you were in really cold wheater, actually i have flu, my throat hurts me when i pass food and water, yeah its cold but like your experience i dont think so, your experience was really extreme, but yeah miners know about the extreme conditions in a mine, we must take advantage of youth, so in the future maybe I can go to a mine at the north pole, hahaha, thank four your comments again 👍
