What is the definition of Longest Human Experiments?

"Longest human experiments" is like the grand finale of a reality TV show where people are subjected to the most grueling, mind-bending, and often downright bizarre tests for the sake of science. Imagine if we tried to make humans dance like penguins or eat a full plate of pretzels for 100 years straight - that's basically what these experiments entail, but instead of a kitchen show, it's a scientific circus!

Edgy example: "We decided to run 'The Great Human Endurance Race' where the longest human experiments would be to test if humans can survive a 100-year stint in a vacuum chamber, only to emerge as the ultimate space aliens."
