What are some activities that I should do on the plane?

I'm going to take a flight(Cathay Pacific) for around 15 hours. I need something to do on the plane so I won't get bored. BTW, are there TVB dramas to watch on the TV screen?

What is a VPN?

VPN is (Virtual Private Network) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia��).
