I'll bite - I'm with you outandabout! Yes it is selfish. Selfish and incredibly short sighted and stupid. The advice is to isolate. The more people get it the more people die. Why is that so hard to comprehend? In addition to that you add to the economic impact by spreading it further. People need to get past the whole 'it won't happen to me or here' mentality and grow up and start listening.
thats not the advice. the advice is to isolate if you have reason to believe you've had contact with someone, or you are feeling unwell.
Outside that, the advice is to maintain social distancing and to continue to go to work, go to school, go about your day as normal but wash your hands more regularly and stay out of peoples personal space. Which in my mind, most people should be doing that anyway!
