"Fret about Covid"
If you were a carer for an adult child with multiple health conditions or lived with an older person with, for example, a history of strokes, then you might "fret about Covid" too.
I hope you are aware that catching Covid increases your risk of strokes, clots in the lungs, cardiac issues, cognitive impairment, vascular issues and the potential for developing Long Covid and Parkinson's disease - which may force you to give up work, or render you unable to care for yourself or your family. Your children, if you have them, may be too ill to return to school if they develop Long Covid.
If you are on Twitter/X you would know that far from a "little pocket of people" who strive to avoid catching or passing on Covid, there are a great number of people who continue to actively avoid exposure to Covid.
Ask yourself why A & E is still overwhelmed. Why GP surgeries are reporting sustained levels of absences amongst clinical and admin staff. Why elective surgeries are being cancelled due to staff ill health.
You sound very ill informed.
