Siblings make kids sad, Canadians killed in Cancun explosion, and time runs out for the Oprah bump

How was your childhood? Unhappy? Science says blame your brothers and sisters. A new British study has found that the more siblings, the unhappier the child. Only children, once thought to be lonely shut-ins, are apparently the happiest of the lot. Possible reasons for this surprising discovery may include family bullying, lack of personal space, parental fatigue and having to fight for a parent's attentions. 

Five Canadians have reportedly been killed in an apparent natural gas explosion at a Mexican resort near Cancun. Mexican authorities report the Canadians were among seven people killed and 15 injured by the blast, which shook the Grand Princess Riviera at around 9:30 a.m. Sunday morning. A nine-year-old boy is among the Canadians killed. The explosion reportedly blew chunks of flooring through the roof and left a crater a metre deep in the lobby of the 676-room resort. Authorities are investigating the cause, but currently suspect a buildup of natural gas under the hotel.

Ever read a book, seen a movie, or bought a skin cream because you heard about it on Oprah? If you answered yes, you've contributed to the Oprah Effect. An article in this weekend's New York Times discusses the end of Oprah's incredible power to create instant fame by simply giving her approval to a person, place or thing. Oprah is credited with bringing numerous people and products into the mainstream, including Dr. Phil, interior designer Chris Madden and Spanx undergarments. Would-be recipients of the Oprah bump are now clamouring to get on the program before it wraps for good this December.
