Questions (Is the ground slightly tilted or is my head tilted?)

It's 5.20am and I am yet to sleep. I feel like this is the time, for me personally, when my brain is at its very peak. It is when we (by that I mean my brain and I, as we are apparently two different entities) think of the real questions.

I know, you may sigh in exasperation.

Anyways, I was watching a Livestream at around 3am and they raised some pretty good questions. Like: "Have you ever peeled an orange so slowly... [then it just trailed off because they started laughing]".

 But it got me thinking... have I ever peeled an orange so slowly? Is there really a rate at which a person can peel an orange which could be universally considered "fast" or "slow"? Is it relative to the size/type of orange? Is a tangerine also an orange? (because there is absolutely no difference to me).

Is time just an illusion? Does the Earth revolve around the sun the other way when we don't sleep? I have so many questions. If anyone can give me some answers that would be very helpful.

Please prioritise the orange peeling question. That is the most important to me.
