The confidence could be due to Hong Kong having the highest life expectancy in the world, with women on average living to 87 years and men 81 years, according to 2016 data calculations by Japan’s health and welfare ministry. The UBS survey revealed 59 per cent of Hong Kong’s wealthy investors believe they will become centenarians, higher than 46 per cent of Singaporean investors and 47 per cent in Taiwan. The survey polled 5,000 high net worth individuals worldwide in 10 markets, including more than 400 individuals in Hong Kong. To qualify, individuals must have at least US$1 million in investible assets. But Hong Kong’s wealthy investors were not alone, as 76 per cent of affluent Germans expected to reach age 100, while the figure for rich Swiss investors was 68 per cent. Meanwhile, only 30 per cent of American millionaires expected to live to 100.
