Health statistics

1) Loneliness could boost Alzheimer's risk: a 4-year long study on group of old people (averaging 81 years of age) found 20% increase on the loneliness was associated with about a 51% increased risk of developing Alzheimer's.

2) Children who get more rest less prone to obesity: sleeping 1 extra hour a night reduced the chance of being overweight from 36-30% in young children, and from 34-30% percent in older children. Similar results were also observed for adults before. Researchers don't know exactly why sleep and childhood obesity may be related, one factor is that lack of sleep may disrupt hormones that influence metabolism and hunger.
