Are meals taken in a group dining hall, or in private rooms? Socialization is vital too. My first cousin died ten days ago at age 95, partly from being isolated in her room at assisted living because of the threat of novel coronavirus. For years, she took part in as many group activities as possible. Her children and their families were not allowed to visit.
Last August I spent one day at good hospital in Washington District of Columbia. I wasn't that sick, but it took several days to recover mentally.
