This guy is analogous to Joe with regards to a number of factors, and he still got so sick that he was hospitalized for weeks. This comparison undercuts a lot of Joe's implied assumptions about COVID-19 and the risk that it poses to himself and the population at large.

Not necessarily. He contracted it at a week long festival, where we can probably safely assume he was doing things not great for the immune system. He's a nurse, which is a high stress job that often leads to high blood pressure and chronic stress, which is also bad for the immune system. He might also work nights leading to vitamin D deficiency. The fact that he lifts and LOOKS healthy doesn't make him healthy, and the fact that he was so sick means that there absolutely was something up with him.

The health outcomes from this are not random.
