Dear Mohamed,
I am writing you this letter because of your sleep, or rather your lack of sleep. You might not
know this, but your lack of sleep can have some serious consequences such as less memory

term memory to long-term memories. Lack of sleep hinders that process from occurring. Matt
Walker also talks about the importance of sleep before learning. “Sleep before learning actually
prepares your brain almost like a dry sponge”, (Walker).
I know you barely get any sleep because of the number of classes you are taking but did you

to age faster. Studies have shown that lack of sleep can age a man by ten years. Men that sleep
only 5 hours compared to men that sleep a full eight hours on average have smaller testicles and
less testosterone, (Walker). This is only the start of your problems if you continue to be sleep-
