It's not uncommon to see students stay awake for insanely long periods of time, especially when out partying and enjoying themselves.
For students at a highly competitive university with an absurd workload, this ability is essential. My hallmates who study medicine often joke that our late bed-times - which normal people would regard as waking-up time - lets them practise for the inevitable sleep-deprived status of being a doctor.
Yet despite exhausting ourselves, we students always find a way to bounce back. We manage to meet deadlines and get the job done.
It amazes me how humans have a phenomenal capacity to achieve great things, especially with the correct motivation.
Marathon runners often complain about hitting 'the wall'. Authors often complain about 'writer's block'. And students just generally complain and complain.
While revising for my finals last May, I remember thinking my brain had reached saturation point. Yet I carried on and somehow managed to learn what I had to.
