Calm down now, it's called hyperbole. You will encounter it a lot, especially online, so don't take everything you read literally.

Also, we are talking 6 hours, not "a few". And depending on your height, seat recline, and problems with lower back pain, you can bet for some people, 6 hours unable to stand up can be quite painful. Not, "bamboo shoots under your fingernails painful" but not something anyone would want to go through.

For me, the claustrophobia of not being able to stand up would be quite terrible.
