Why do you become physically tired when you push against a wall and fail to move it even t?

Surprisingly, there is actually work being done! However, if a single person's just leaning against a wall, pressing their weight actively into it, there's not enough pressure being exerted on the wall to make it move. It does experience the pressure, but the other forces of the rest of the wall pressing in on it, gravity holding it together, all push back more. As well, even if no work was truly being done against the wall, locking your arms in one spot and applying pressure to your own muscles works those muscles to fatigue.

Not sure if this is a real physics question... but yes, pushing against a wall is tiring even though no "work" is being done. Its isometric conditioning.

Why should you not use even though?
There's nothing wrong with using "even though." I imagine you've had a teacher caution you against starting a sentence with "even though" because you've been writing fragments or incomplete sentences. For example, if I say "Even though I was tired," you'd wonder why I said "even though." I could just say "I was tired." Or I could finish the rest of my thought in a single sentence: "Even though I was tired, I stayed up late to finish my homework."
