science is a wonderful thing. It's amazing in fact. However, I don't wish to live my life governed by it. I quite enjoy common sense and a little dose of free thinking
I think though that it is unreasonable to ask others to live that way, at this time. You can do that in your home, and in spaces, but you can't inflict your desire to ignore science onto others, when it could harm them.
I was a smoker when the smoking ban came in, and I supported it. The science was that my smoking was bad for the health of others.
IMO the lift question is similar - you not being free to chat is a lesser harm than someone else catching covid from you in the lift.
I also am completely sceptical about the idea of acknowledging something is scientifically justified and describing doing the opposite as common 'sense'. What that actually is, is common 'foolishness'. We all do things that are contrary to scientific advice, but doing so has nothing to do with sense.
Free thinking is irrelevant, I am a free thinker whether I choose to heed a warning or ignore it. The presence of workplace h&s rules in no way limits my free thinking.
