The researchers found that while small toy parts can pass through the digestive system of healthy adults without causing harm, children are more likely to experience blockages, perforations, or other serious injuries.
Six Scientists Swallow Lego Heads To See How Long It Takes To Poo Them Out

To determine how long it takes to poop out Lego figureheads, six experts each consumed one.
To be honest, all I can say is that I'm glad to see that science is now prepared to take on major issues.
Yes, even though it sounds like a joke, pediatric healthcare workers did intentionally consume the small Lego heads for a study titled Everything is Awesome: Keep the Legos in mind.

No chance of ignoring it while you wait for it to reappear in the toilet bowl, right?
The extremely serious and crucial research used two scoring systems: Found and Retrieved Time (FART) and Stool Hardness and Transit (SHAT), both of which are names for the same thing. They were referred to as that, in all honesty.

The SHAT score was actually divided into two parts: the pre-SHAT score, which recorded the researchers' regular gastrointestinal movements, and the post-SHAT score, which was recorded after the Lego head was ingested.
Then, information was collected by comparing the pre and post-SHAT scores.
The FART score, on the other hand, was a little gloomy - if you can imagine - and required the participants to search through their feces for a tiny yellow head in the days after swallowing.
The study did have a serious goal, despite the fact that it may have seemed like a joke at first and was undoubtedly difficult for the researchers to explain to their loved ones.
Children love to consume things that aren't meant to be eaten, as any parent of a young child can testify, often with very dangerous consequences.
Ingesting Lego by accident or on purpose generally has no negative effects, but in order to ease parents' concerns, our brave researchers set out to determine how long it takes for a Lego head to pass through a human digestive system.
What then did our courageous experts learn?
The study's FART score averaged 1.71 days, which means that the Lego head usually emerged from the body in less than two days.
The researchers wrote in an analysis of their results: “A toy object quickly passes through adult subjects with no complications. This will reassure parents, and the authors advocate that no parent should be expected to search through their child's feces to prove object retrieval.” Good point, well made.
