81％ 的人天生自带免疫力。

“Scientists are now showing evidence that up to 81% of us can mount a strong response to COVID-19 without ever having been exposed toit before:

Cross-reactive SARS-CoV-2 T-cell epitopes revealed preexisting T-cell responses in 81% of unexposed individuals, and validation of similarity to common cold human coronaviruses provided a functional basis for postulated heterologous immunity.

This alone could explain WHY the Herd Immunity Threshold (HIT) is so much lower for COVID-19 than some scientists thought originally, when the number being talked about was closer to 70%. Many of us have always been immune!“

As the author points out, we should have known from the incident on the Diamond Princess (Cruise Liner) that immunity was far more widespread than previously thought. Readers might recall that only 17%of the people on board tested Covid-positive, “despite an ideal environment for mass spread, implying 83% of the people were somehow protected from the new virus.”

Think about that for a minute. All of the passengers were 60 years old or older, but only 17% caught the virus. Why?

Immunity, that’s why. What else could it be? Cross immunity, natural immunity, or SARS-CoV-2 T-cell immunity. Whatever you want to call it,it exists and it explains why the vast majority of people will not get the highly-contagious Covid no matter what they do.

你很聪明 我们这里，口罩有愈演愈烈的趋势，有些商家要求顾客带口罩才能进。一群傻子！

因为我觉得

如果一个人，真正在乎自己的生命

就不要乱扔垃圾，制造那么多污染

不要贪得无厌，用物质来满足自己无限的欲望

这些都是对生命有害的

这些都做不到，还戴口罩有何用？
