The problem is the people like me who DO rewatch youtube videos. There are a bunch of "Comfort food" videos I turn to sometimes. Like you would rewatch a movie you really enjoy.

But that's the real problem. You can't just average everyone and apply that result to anyone. The "average of everyone" fits exactly NO ONE.

The US Navy figured this out long ago in a famous anecdote in fact. They wanted to fit a cockpit to the "average" pilot, took a shitload of measurements of a lot of airmen, and it ended up nobody fit.

The actual solution was customization and accommodations.
