Input: Consider Input: Iron deficiency is the most common nutritional disorder affecting at least one third of world's population. Though anemia is common manifestation of iron deficiency, other effects of iron deficiency on various tissues, organs and systems are usually under recognized. Impaired brain development and cognitive, behavioural and psychomotor impairment are most worrisome manifestations of iron deficiency. Studies have demonstrated that some of these changes occurring during period of brain growth spurt (<2 years age) may be irreversible. Association of iron deficiency with febrile seizures, pica, breath holding spells, restless leg syndrome and thrombosis is increasingly being recognized. Impaired cell-mediated immunity and bactericidal function are generally noted in iron-deficient persons; however, the findings are inconsistent. Despite proven reversible functional immunological defects in vitro studies, a clinically important relationship between states of iron deficiency and susceptibility to infections remains controversial. Studies from malaria endemic regions have reported increased incidence of malaria in association with iron supplementation. These and some other aspects of iron deficiency are reviewed in this article.

Output: Which deficiency is the cause of restless leg syndrome?


Input: Consider Input: One day Mr. White gave his wife ten pounds for her birthday -- ten new pound notes. So Mrs. White went out shopping. She waited for a bus, got on it and sat down next to an o1d 1ady. After a while, Mrs. White noticed that the old 1ady's handbag was open. Inside it, she saw a wad of pound notes exactly like the ones her husband had given her. So she quickly looked into her own bag -- the notes had gone! Mrs. White was sure that the o1d lady next to her had stolen them. She immediately thought of calling the police. But as she disliked making a fuss , she decided to take back the money from the old 1ady's hand bag and say nothing about it. She looked around to make sure nobody was watching. Then she carefully put her hand into the o1d lady's bag, took the notes, and put them into her own handbag. When she got home that evening, Mrs. White showed her husband the beautiful hat she had bought. "How did you pay for it?" Mr. White asked. "With the money you gave me for my birthday, of course" she answered. "Oh? What's that, then?" he asked, as he pointed to a wad of pound notes on the table.


Output: Why did Mr. White give his wife ten pounds?
