There is an assumption here that long-term mostly mild symptoms are unique to COVID instead of prevalent. There is an assumption here that such things are cumulative and will threaten everybody.

The reality seems to be much more like long term disease side effects are relatively common, extremely difficult to diagnose, and just starting to be understood.

For example there have been recent publications indicating the Epstein-Barr virus (EBV, often called "mono") is a cause or potentiator of multiple sclerosis.

We also have "chronic fatigue syndrome" and "fibromyalgia" which are essentially just clusters of symptoms with no known definitive cause which are quite possibly "Long-<disease X>" among others.

You're also neglecting the long term psychological and other effects of lockdowns.

It is not clear that the benefits of forced lockdowns or forced vaccinations beat the alternatives or that such things are justifiable in a free society... and if you want to live in a dystopian society that matches your morality I suggest you move to one.

As for me the cost/benefit of lockdowns has become clear to me and I'll vote with my feet if faced with another one.
