Sleep

Sleep is a naturally recurring state of mind characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings. It is distinguished from wakefulness by a decreased ability to react to stimuli, but is more easily reversed than the state of hibernation or of being comatose. Mammalian sleep occurs in repeating periods, in which the body alternates between two highly distinct modes known as non-REM and REM sleep. REM stands for "rapid eye movement" but involves many other aspects including virtual paralysis of the body.

During sleep, most systems in an animal are in an anabolic state, building up the immune, nervous, skeletal, and muscular systems. Sleep in non-human animals is observed in mammals, birds, reptiles, amphibians, and fish, and, in some form, in insects and even in simpler animals such as nematodes. The internal circadian clock promotes sleep daily at night in diurnal species (such as humans) and in the day in nocturnal organisms (such as rodents). However, sleep patterns vary widely among animals and among different individual humans. Industrialization and artificial light have substantially altered human sleep habits in the last 100 years.

Ceremony

A ceremony (UK /ˈsɛrɪməni/, US /ˈsɛrəˌmoʊni/) is an event of ritual significance, performed on a special occasion. The word may be of Etruscan origin, via the Latin caerimonia.

Ceremonial occasions

A ceremony may mark a rite of passage in a human life, marking the significance of, for example:

In some Asian cultures, ceremonies also play an important social role, for example the tea ceremony.

Mr. Bean

Mr. Bean is a British sitcom created by Rowan Atkinson and Richard Curtis, and starring Atkinson in the title role. Atkinson co-wrote all fifteen episodes with either Curtis, Robin Driscoll, or both, with Ben Elton co-writing the pilot. Thirteen of the episodes were broadcast on ITV, from the pilot on 1 January 1990, until "Goodnight Mr. Bean" on 31 October 1995. A clip show, "The Best Bits of Mr. Bean", was broadcast on 15 December 1995, and one episode, "Hair by Mr. Bean of London", was not broadcast until 2006 on Nickelodeon.

Based on a character originally developed by Atkinson while he was studying for his master's degree at Oxford University, the series follows the exploits of Mr. Bean, described by Atkinson as "a child in a grown man's body", in solving various problems presented by everyday tasks and often causing disruption in the process. Bean rarely speaks, and the largely physical humour of the series is derived from his interactions with other people and his unusual solutions to situations. The series was influenced by physical performers such as Jacques Tati and comic actors from silent films.
