Sorry I didn't know how to translate it and used google translator for breath tube. And thanks for responding. Well I think it's more likely that I wil die because I open my mouth than this virus.
Well take care, I hope your government isn't as retarded as mine.
One question do you need to get 3 people (without anesthetist) to put it? Nobody had the thought that a virus that have high infectus rate would exist in the bio weapon era?
