You don't know Pain until you've studied Engineering

I totally ripped this list of a fb group called:
"Childbirth? ... You don't know Pain until you've studied Engineering"
I've only taken the ones that I personally felt haha... the list is way more extensive than this,

You know you're studying engineering when…

You come out of a lecture and feel that you wouldn’t mind being hit by a bus.

You are doing maths that the maths students don’t cover until the 2nd year.

You know the Greek and Arabic alphabets better than the language students.

A 4 hour day is an easy day.

A 9 hour day is still an easy day.

You are up at 3am in the morning trying to finish yet another piece of coursework asking yourself… why?

You feel bitter contempt towards anyone complaining of 2 lectures in a row.

Someone complains about ‘take away exams’ you feel a sudden urge to hospitalise them.

It’s the norm that you can’t fit an equation on 1 line of a page.

Handing in an assignment just means that’s there’s a new one to complete.

Time is measured in submission deadlines.

You find out you have 3x as many exams as practically everyone else.

You frequently ask yourself why the fuck are you doing this.

You are used to covering a ridiculously large span of subjects to the same standard as the respective degree students.

Breasts in a lecture theatre generally means there's a guy who's let himself go a bit.

You would assume a horse is a sphere to make the maths easier.

Your best friend is your calculator.

Things I've added to the list:
You've wondered if the alcohol in the lab could make the hours a little easier and have contemplated adding a squirt into your coffee.

You've been warned that the chemicals used in your experiments are cancerous/ you could potentially be exposed to radiation/ your equipment has the capacity to electrocute the motion out of you or slice your fingers in a heartbeat.

You start appreciating classmates for basic things like showering at least once a day.

You tend to know at least 70% of your classmates and most of their wardrobe because you see them almost every day (refer to lecture hours point above) and because each year, the class size dwindles and no one really has much fashion sense.
