I recall watching a video years ago about coffins for some reason. It mentioned how in the US the coffin industry has to make much bigger coffins since people are much bigger. The reporter somewhat jokingly asked "Is there a coffin season?" like chocolate is for Valentines/Hallow'en or toys for Christmas. The owner of the coffin business said "Yes flu season is our busy time." their sales double. That documentary was years before COVID hit.
