[EX Q]: Princess Kate  pregnant with  her  third child  made  her  first public appearance in six weeks to join Prince William and Prince Harry at Buckingham Palace to mark World Mental Health Day.
 Kate   35  showed a slight baby bump beneath the tea-length Temperley dress  she  wore to the event  thanking supporters for helping to change public perceptions about mental health.

"The Duchess' condition is improving but she is still suffering from hyperemesis gravidarum " an aide to Princess Kate said today. "The Duchess is delighted to be here tonight."

JERSEY CITY  New Jersey (Reuters)  - Tiger Woods  said  he  was âoptimisticâ about  his  golfing future while at the same time publicly acknowledging what has been obvious for some time  that  he  might never return to competitive golf.

âYeah  definitely. I donât know what my future holds for me â  he  said on Wednesday on the eve of the Presidents Cup when asked whether there was a scenario that would not allow  him  to compete again.
âI donât know what 100 percent (healthy) means after eight surgeries  but Iâll try and get as close as I can to that number â  Woods  added.
 Woods  was peppered with questions during a news conference with his three assistant Presidents Cup captains and the four International assistants  who often looked bored at the focus stayed on the second most prolific major champion of all time.

[EX Q]: "Petrocaribe will be strengthened -- independent of the international situation  independent of the price of oil " Venezuela President Hugo Chavez said as he arrived Friday in St. Kitts.
 His country's state Bolivarian News Agency said Petrocaribe leaders meet "with the expectation of its expansion  as well as new programs of cooperation and attention to a world increasingly thirsty for fuel."
 During the meeting  Chavez called the pact a geopolitical and social "offensive for unity " and said Venezuela is open to accepting other nations. "If some countries want to join  the doors are open " he said.
 The plan promotes Chavez's vision of regional independence from the United States  and the lure of cheap oil has drawn countries friendly to Washington as well as his leftist allies.
