SINGAPORE - Two months ago, Mr Abel Ang, chief executive of Advanced MedTech, said to be the largest medical device company in South-east Asia, wrote a column in The Sunday Times about his simple life living well within his means in an HDB flat and travelling by public transport.

The 46-year-old, who is also an adjunct associate professor at Nanyang Technological University, did not expect the reaction to his piece. More than 10 readers sent him messages on the issue via LinkedIn and other platforms.
