Residents of Key West Convalescent Center waits to be evacuated in preparation for Hurricane Ike in Key West, Florida September 7, 2008. Hurricane Ike barrelled toward Cuba as an extremely dangerous Category 4 storm on Sunday and was forecast to sweep into the central Gulf of Mexico as a large and powerful storm echoing Hurricane Gustav. The densely populated Miami-Fort Lauderdale area in south Florida seemed an increasingly less likely target, but visitors were ordered to flee the vulnerable Florida Keys island chain on Saturday.

Patients Chung Kong Tuck (L), 72, and Wong Hong Jee, 85, rest at the HCA Day Care Centre in Singapore September 19, 2007. Every week, around 50 elderly terminally ill patients spend the day at the centre, where they participate in rehabilitative and social activities such as singing, arts & crafts and pet therapy. Providing healthcare and eldercare services for older Singaporeans is a major objective by a government committee set up to prepare for an ageing society. According to a 2006 report by the committee, by 2030 the number of Singapore residents aged 65 and older will multiply threefold from 300,000 to 900,000, or one in every five residents.
