This Mar. 24 excellent video from a senior infectious-diseases doctor in Korea (one of the countries with the best COVID-19 response) hits the nail on the head: what makes this virus so dangerous for the otherwise-healthy, but not-so-young, crowd is IMMUNOSENESCENCE - the link here is cued to that part.
Future attempts to secure better funding for Anti-Aging research ought to really emphasize this to avoid such pandemias like SARS and/or others alike. It looks like it's not the virus but an overwhelmed senescent immune system reaction that kills the elders.
