A lack of sleep affects your mood

When a person cannot sleep or sleeps only a few hours a night, a lot of damage is done. A person gets bad-tempered, loses their drive, feels angry and tired, and also gets bags under their eyes. Poor sleep can also make a person emotionally unstable and even affect their immune system. A good tip to improve the quality of sleep is to avoid heavy meals at night and to avoid drinking beverages with a high caffeine content, such as soft drinks and coffee.

Why I stopped mispronouncing my Igbo name

In Nigeria, the language spoken by one of the largest ethnic groups, the Igbo, is in danger of dying out – which is odd because the population is growing. In the past this didn’t worry Nkem Ifejika, who is himself Igbo but never learned the language.

When he is in Nigeria, he says his parents are Igbo. He might throw in that he partly grew up in the United Kingdom. In Britain, He says he’s Nigerian, though he often adds explainers about having been educated at British schools and lived outside Nigeria since he was 12 years old.

Nkem Ifejika can speak English, French among others. However, he can’t speak the language of his ancestors. Igbo is a tonal language, so the words with the wrong stresses and tones either change their meaning, or worse, become unintelligible. In Igboland, as it’s informally known, names have meaning and history. Nkemakonam means “may I not lack what is mine”, while Ifejika means “what I have is greater”. By mispronouncing his names, he was throwing away generation of history, and disregarding his parents’ careful choice.

His indefatigable and proudly wife, who is also Igbo, helped him out when they met. Now he knows how to pronounce his name properly, with the correct tones and with pride.

According to the article, Nkem Ifejika ___________, except:

The Crab and His Mother

Mamma Crab _____ to Baby Crab when she _____ that he was walking sideways. Mamma Crab said, ‘Why are you walking sideways like that, my son? You have to walk straight.’ Baby Crab replied, ‘Show me how, dear mother, and I’ll follow your example.’

Mamma Crab tried and tried, but her efforts were in vain. She could not walk straight herself. Then, she saw how foolish she had been to find fault with her child.
