Longer life expectancy?

An elderly man was found dead in his own house in Singapore recently. Police believe that he had been dead for 6-12 months before they found him.

There was a news article on this and one paragraph caught my attention -

"Most Singaporeans live in densely populated public housing estates like Tan's because of land scarcity, and an increasing number of elderly citizens live on their own due to longer life expectancy."

He was 69... Live alone due to longer life expectancy?? What does that mean?

Singaporeans know that the sentence should have been read : "...and an increasing number of elderly citizens live on their own due to the lack of welfare in the country."
