Somewhere, at this very moment, someone is mildly tired and a little sore. He has ​had these symtpoms ever since he bought that new mattress a year ago, but the manufacturer assured him that this will be the last mattress he ever needs to purchase. Rather than blaming an impulse buy or failing to check the product reviews, this person is convinced that he has long covid and will be for the rest of his life. He will never purchase another mattress.
