Sleepwalking is a disorder that causes people to get up and walk while they're asleep. It usually happens when a person is going from the deep stage of sleep to a lighter stage or into the awake state. The sleepwalker can't respond during the event and usually doesn't remember it. In some cases, he may talk and not make sense.
When someone sleepwalks, they might quietly walk around their room. Or they might run or attempt to "escape." Typically, the sleepwalker's eyes are open with a glassy stare as he roams the house. If you question him, he'll be slow to respond or not respond at all. When you get him back to bed without waking him up, he usually won't recall the event. Older children may wake up more easily at the end of a sleepwalking episode.
In 2010, 32 % of men and 26 % of women were normal weight. By 2050, the proportion of normal weight will decrease to 12 % and 9 % for males and females respectively, and more people will be obese than overweight. It is projected that by 2050 there will be 12 million cumulative incidence cases of diabetes and 8 million cumulative incidence cases of heart disease alone. For the thirteen diseases considered, costs of $US 806 million are estimated for 2010, projected to increase to $US 1·2 billion and $US 1·7 billion in 2030 and 2050 respectively. A 1 % reduction in BMI prevalence could save $US 43 million in health-care costs in 2030 and $US 85 million in 2050.
