Someone asked a question on FaceBook:
Has anyone lived long enough to buy a second bottle of Worcestershire sauce?
I have easily emptied at least 6 large bottles as an adult, so that is easily more than one per decade of life. I remember buying a two-pack of bottles at Sam's Club once. I use Worst Sauce less now that I brought oyster sauce into my food prep several years ago but most likely less than ten. I still use Worse Sauce in my prep of Southwest Stew, which has been made 90 times at 1 tsp per batch, so 15 fl oz. and that would be 3/4 of a bottle of Worst Sauce consumed by just that one recipe in the 4 years & 4 months since starting The Stew.
I also use Worst Sauce to modify (already spicy) Spicy V-8 juice. I put in Worst Sauce, Sugar, and Tabasco sauce, 17.5, 66, and 5.4 grams according to the recipe that I have wrote directly onto the inside door of one of my kitchen cabinets.
I have seen reports from very old people who claim that Worst Sauce has allowed them to live past 100 years.
