Work-life balance: Hongkongers, it's time to go home

You need only look down the MTR platform at the sea of 1,000-yard stares to know that this city has a work problem - let me rephrase that: a work addiction problem.

UBS' annual city-by-city survey shows Hongkongers work an average of 2,606 hours per year. That's almost 600 hours more than Tokyoites (2,055 hours a year); Parisians, on the other end of the scale, get 1,002 more hours per year with their loved ones than we do.

Let's concede that the legal and financial industries are some of the biggest employers in the city, and jobs in those sectors can require long hours. Geography is an issue, too. If you're in a global business, Hong Kong sticks you in the time zone that takes calls at 10pm.

Here's the thing. There are two characteristics of all addictive stimuli: that they increase the likelihood that a person will seek repeated exposure to them; and that they are intrinsically rewarding, or perceived as being desirable, says Dr Eric Nestler, a specialist in the biological nature of addiction.
