Really sad, but sh!t happens. One of my daughter's coworkers - health fanatic went for morning run 3 or 4 times a week. One day he didn't return from his run so they went looking for him and found him dead. age - somewhere in the 30 - 35 range no history of heart problems. This was ten years ago. another one of her coworkers was walking down the corridor in the hospital and collapsed. heart problem - no prior indications of heart trouble, and luckily he was in the hospital when it happened, so he survived - age 41. Again long before covid.
I see on the pictures a tat and a nose ring, while this doesn't prove anything, it is an indication of the modern millennial life style where tats, body piercings and recreational drugs are considered the norm.
