#2 OF THOSE WEIRD THINGS HUMANS DO,AND WHY WE DO THEM

#2. SLEEP
We spend roughly one-third of our lives asleep.
No human can go without it for more than a handful of days, and yet sleep may be the least understood of all our activities.

It certainly allows for a lot of body "maintenance work," from production of chemicals that get used during waking hours to the self-organization of neurons in the developing brain. REM sleep, with its high neuronal activity, occurs for longer each night during periods of brain growth.

Several theories point to sleep as a state vital to memory and learning. It may help ingrain episodic memories into long-term storage, and it also may simply give our mental waking activities a much-needed break.
