Hello ladies and gents this the Viking telling you that today we are talking about

WEIRD OR WHAT

Hiccup

Hiccups are involuntary spasms of the diaphragm the muscular membrane in your chest that figures importantly in breathing. A spell of them ensues when that muscle gets irritated, often by the presence of too much food in the stomach, or too little.

Weirdly, though, hiccups are as useless as they are annoying; they serve no apparent purpose. One hypothesis suggests they may be a remnant of a primitive sucking reflex. Whatever the ancient function, they are little more than a nuisance now something to be gotten rid of via a variety of creative folk remedies.

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.

Dream

Sleep seems to serve a vital function for us humans, but what about dreaming? It's something we do almost nightly, but does it serve a greater purpose?

The truth is that scientists aren’t completely sure why people dream. However, theories on the purpose of dreaming abound. One theory, proposed by Harvard University psychologist Deirdre Barrett, suggests that humans dream in order to solve problems. More specifically, the highly visual (and sometimes completely illogical) landscape of dreams help us think differently about our problems than we would in waking life. This "out-of-the-box" thinking might help people solve problems that they just can't resolve while awake, according to Barrett.

Other dream researchers, like Boston University neuroscientist Patrick McNamara, think dreaming facilitates creativity in waking life.
