Coronavirus and Covid-19 Rumination #5

By Rud Istvan – Re-Blogged From WUWT

The world continues to learn about this sometimes deadly new zoonotic virus. We know now from NYC that it is disproportionately serious in males (61% of tested symptomatics), more fatal in people over 65 (63%), and is disproportionately lethal (84%) in people with especially the comorbidities hypertension (55%), diabetes (35%) and obesity (50% of serious/critical [s/c] hospital admissions in NOLA, under 60 years old 2x s/c in NYC). More on the significance of these facts is developed below.

We know from two inadvertent extreme ‘lack of social distancing’ “experiments”, Diamond Princess (DP) and CVN71 (Theodore Roosevelt, TR), that only about 15% (TR) to 19% (DP, with several more weeks of exposure) ever test positive for the virus. That means that something like 80-85% of people have an immune system that seems to handle the virus effortlessly even in highly infectious, high viral titer circumstances–so that not even a positive viral shedding test develops. This could just be a very good innate immune system; it could also be a primed active immune system (i.e. the population was NOT naïve). A very plausible explanation hypothesis is developed below with important ramifications for opening countries from extreme lockdown measures.

Evening Workouts May be Better for Men With High Blood Pressure

By Thomson Reuters – Re-Blogged From Newsmax Health

Men being treated for hypertension may find that exercising at night, rather than in the morning, helps reduce their blood pressure readings, a small experiment suggests.

Researchers randomly assigned 50 men with hypertension, or high blood pressure, to one of three exercise regimens: cycling three times weekly for 45 minutes between 7 a.m. and 9 a.m., or doing the same between 6 p.m. and 8 p.m., or stretching three times weekly in the morning or evening for 30 minutes. After 10 weeks, researchers found that only evening workouts were associated with meaningful reductions in blood pressure.
