Slightly irrelevant to the game, but I guess a message to the few people who are here. If you live in a colder country, stay warm, dress yourself up and keep yourself aware. I've already fallen ill, and all it took was one walk around a mall, with a cold wind blowing down my neck on the way to the car. Not the most convenient situation to have right now, especially during covid. Strap yourself up and stay clean. Don't become just another number on that list we hate to see keep rising.
You can only get viruses from someone/something with the pathogen on it, not cold weather or being cold.

I have walked at 5am, -20 celcius without sun, went home at -10 celcius with no sun again, and not even once got a virus. The last time I got a flu, was in 2018 and it was through a kiss from a very infected person.
