Did you smell and/or taste the egg at room temperature before it was added to the smoothie? From personal experience, it's a bad idea not to. ;-)
It's easy to tell when an egg has gone bad, but not easy to tell whether it's contaminated with salmonella.
Really, in the past 100 years of refrigeration and Pasteur, I would hazard a guess that more people have died or become seriously ill (per capita in the relevant regions) from food contamination than in the preceding 100 years, simply because before refrigeration we had a much higher probability of smelling any contamination.
I'd take a bet on that. I haven't read any statistics on this, but I have read that before refrigeration, people were often less picky about what constituted expiration in food, by necessity. People might be able to smell most dangerous food contamination, but before refrigeration and pasteurization, people were often faced with a choice between eating potentially dangerous food and not eating. I recall Bill Bryson writing (in Made In America) that a contemporary noted that at one meal, George Washington put away his food without eating it, because he thought it was off. His wife cleaned her plate.
I am beginning to suspect that it is surprisingly common for intelligent, competent adults to somehow make it through the world for a few decades while missing some ordinary skill, like mailing a physical letter, folding a fitted sheet, depositing a check, or reading a bus schedule. Since these tasks are often presented atomically - or, worse, embedded implicitly into other instructions - and it is often possible to get around the need for them, this ignorance is not self-correcting. One can Google "how to deposit a check" and similar phrases, but the sorts of instructions that crop up are often misleading, rely on entangled and potentially similarly-deficient knowledge to be understandable, or are not so much instructions as they are tips and tricks and warnings for people who already know the basic procedure. Asking other people is more effective because they can respond to requests for clarification (and physically pointing at stuff is useful too), but embarrassing, since lacking these skills as an adult is stigmatized. (They are rarely even considered skills by people who have had them for a while.)
This seems like a bad situation. And - if I am correct and gaps like these are common - then it is something of a collective action problem to handle gap-filling without undue social drama. Supposedly, we're good at collective action problems, us rationalists, right? So I propose a thread for the purpose here, with the stipulation that all replies to gap announcements are to be constructive attempts at conveying the relevant procedural knowledge. No asking "how did you manage to be X years old without knowing that?" - if the gap-haver wishes to volunteer the information, that is fine, but asking is to be considered poor form.
(And yes, I have one. It's this: how in the world do people go about the supposedly atomic action of investing in the stock market? Here I am, sitting at my computer, and suppose I want a share of Apple - there isn't a button that says "Buy Our Stock" on their website. There goes my one idea. Where do I go and what do I do there?)
