Bigger brother than the one already in place in many countries, and growing in others.... here we come. Puhlease, this is absolute crap. My eyes water every time it gets below a certain temperature. I get a fever every time the seasons change due to high allergic reactions. My nose runs when it's cold. I cough when hit by a dust storm, or when I am chocking on something. My feet run when I am being chased. No drone is ever going to be able to distinguish between a normal cold and something more diverse, unless there is a possible visible absolute skin reaction, such as blotches etc. No drone will ever be able to tell if I have one sickness or another. This is just a new way to make money out of fear and disinformation.
