To people who don't want to wear masks or get vaccinated, I have this to say. You're part of a society, wherever it is you may live, and there are many benefits to living in a society. Society allows us to have a career/job, gives you easy access to food and housing, and generally makes your life easier in every possible way.
What's the alternative? Moving out to the woods, building a cabin, and foraging for your own food.
So because we all benefit from society, when it needs something back from us, like wearing a mask and being vaccinated, or simply just following basic societal laws, it's our obligation to do so. Life is about give and take, not just what we personally want or prefer.
That is all.
