Of course Covid is unstoppable. You should:
1. Hug as many different people as you can;
2. Kiss as many different people as you can;
3. Get as close to as many people as you can;
4. Spend lots of time at the beach, walking around town, in the sunshine;
5. Get on with business and your life.
Why do all this? Because, like as Covid is unstoppable, even so natural herd immunity is unstoppable.
What you can expect is to get the flu or a cold a little. It will go away in most people, just like the flu or a cold always does.
If you have some weakness - bad heart disease, bad cancer, bad diabetes, bad any disease, or if you are over 65 - then protect yourself by staying out of harm's way. But if you are generally healthy, get together with other people, and get your herd immunity.
Eat well, sleep well, and take vitamin C, zinc, vitamin D3, and vitamin A, in greater quantities than usual. These will help to strengthen your body... possibly enough so that when you get Covid, you won't even feel the symptoms.
Note that if you are on medication, consult your physician about which nutrients you should not take. Get a second and third opinion.
Here is the most important part. I said it above, but I will say it again. It's attitude.

Rather than quarantining, do the natural science that we have done for thousands of years... the thing that we know works. Stop the lockdowns and shutdowns. In addition to stopping Covid, this will improve our attitudes, and it will let us get back to work so we find satisfaction in life.
