If you're looking to escape the horrendous air pollution during the winter and spring, there are no alternatives in the north. The best option is 6 months on 6 months off. Spend half the year in another part of the world.
Our boosters are all up to date and we are still double masking with N95 class protection whenever we leave the house so I'm reasonably confident we will survive the next phase. It's better to be safe than dead folks! Double masking is not expensive. We buy them by the 100 pack and they are very very reasonably priced. Well worth the money. I think everybody needs to ask themselves. What's your life worth? Stay safe folks. ????
