To paraphrase Dean Wormer from Animal House, “Fat, drunk and Vitamin D-deficient is no way to get through the pandemic, son.” There's nothing definitive yet, but it appears the best protection from the virus may be to improve your eating habits, refrain from drinking yourself into a stupor, and go for a walk in the spring sunshine. In particular, sunshine on the skin helps develop Vitamin D, which seems to be beneficial in fighting off the virus. Yes, healthy people with no known health problems have gotten and died from the disease, but there is no argument that by far those most susceptible are sedentary people with pre-existing health problems, people more likely to be sitting inside on their ass, even if that is not their choice.
Studies show that there has been no significant difference in progress of the disease between European countries that had no lockdown (Sweden) versus those that had police-enforced house arrest (Hungary). Somewhere, an authoritarian is weeping...no, they're not weeping, they are suppressing this information. "Experts have expressed concern that Sweden's refusal to implement a lockdown will lead to increased deaths," according to a German news site. "Expert" opinions that so far are not backed up by the evidence. "We who are adults need to be exactly that: adults. Not spread panic or rumors," Prime Minister Stefan Lofven said early on in the pandemic.
It is sad that the old and frail are dying in disproportionate numbers, but having everyone else hiding inside their houses does not help them. Nursing homes will not be allowing visitors anytime soon whether there is a general lockdown order or not. Be prudent and practice social distancing, but stop hiding. Get some sun.
