Yes I have forgotten to cover my sneeze more than once in the last thirty five years. Yes I still think it is not a good thing to do. What kind of a question is this man. Do you think that as soon as you break any social norm you relinquish your right to object to any normalization of this stuff for the rest of your life 😔
I believe the academic label for your concern is the mind-body problem, or the hard problem of consciousness which specifically questions the gap in explanation between the physical process and the subjective experience. Going against the grain of the OP picture, this is definitely still firmly within the realms of philosophy, not at all a settled science.
