So you thought setting your date of birth validator to accept anyone under 150 years old was being GENEROUS and INCLUSIVE? Congratulations, you've just granted Pharaoh Ramesses II a valid passport in 1976. The man died in 1303 BC and somehow your validation logic was like "yeah, seems legit, he's only 3,279 years old, well within our acceptable range!" This is what happens when developers write validation rules at 2 PM on a Friday thinking "nobody will EVER need to enter a date that old." Meanwhile, Egypt's out here issuing official government documents to mummies for restoration trips to France, and your form is just nodding along like "welcome aboard, your majesty." The real kicker? Someone at the Egyptian passport office in 1974 had to manually enter "-/+/1303 BC" into whatever system they were using, and it WORKED. Edge cases aren't just theoretical anymore when you're dealing with royalty that's been dead for three millennia. Maybe next time set that validation to "must be alive" instead of just "reasonably old."
