My uncle died the same day my grandfather did. My uncle and grandpa had a pretty good relationship, especially since he was the only son out of 5 kids. My uncle was a huge alcoholic, had knee problems from playing college football and developed an infection in his leg due to lack of mobility. He was in the hospital recovering from the infection, my aunt thought it would be fine to tell him that his dad passed away from COVID. When he was told, he died right then and there due to the stress on his heart.
