A significant proportion of people in the USA have problems with their blood sugar levels. North Americans eat too much, eat the wrong foods and don't exercise. They tend to suffer from blood-sugar disorders (which then cause cancer and, well, everything).

Blood-sugar disorders are so varied in their symptoms as to exhaust listing here. People so affected are best described metaphorically as "human shipwrecks". New York Times had an excellent series on diabetes years ago:

Skip to the section "Shortages and Shipwrecks", read it and weep: this was years before Covid and we had an epidemic that nobody was paying attention to. Covid is leaving and we still have a diabetes epidemic.

Very few young people are dying from Covid in the USA. The vast majority of deaths have been in the age 65+ group. However, the USA does have an exceptionally high obesity rate and we know that greatly increases the risk.
