They say time heals all wounds, but it’s also our rarest commodity.

So much has happened over the course of our entire history that there’s bound to be some knowledge that falls through the cracks.

As it turns out, that missing information sometimes turns out to be way more crucial than initially thought.

Man, this information sure could’ve come in handy throughout, like, most of the 19th and 20th-century.

The sad thing is, this isn’t the first obvious solution from the past that people have overlooked.

Too bad for institutional biases.

So many solutions were just totally ignored.

Honestly, I didn’t even think about how “milk” could be totally misinterpreted. With all that in mind, it makes a lot more sense how the Romans’s concrete recipe might appear a little more vague at first glance.

Well, that was an absolute trip. Who knows what other pieces of wisdom will be lost to time? After reading that thread, I’m convinced there are more ancient secrets out there. Let’s just hope that the ones we still haven’t uncovered aren’t too drastic.
