Pornsak Bowornsrisuk talks to a colleague while running a bus terminal in downtown Bangkok, Thailand, February 3, 2016. Pornsak Bowornsrisuk pulls an umbrella towards him to shield his head of thick grey hair from the blazing sunshine at the Bangkok bus terminal he manages. "You've got to be damned tough to do this job," says the 63-year-old, who records bus arrivals and departures, and tots up fares collected from journeys across Thailand's capital. The World Bank estimates the working-age population will shrink by 11 percent by 2040, the fastest contraction among Southeast Asia's developing countries. Thailand's stage of economic development, the rising cost of living and education, and a population waiting longer to get married are among the reasons it is ageing more quickly than its neighbours. An effective contraception programme in the 1970s also played a part, said Sutayut Osornprasop, a human development specialist at the World Bank in Thailand. Picture taken February 3, 2016.
