How do you sit when you use a Laptop?

 I sit before the laptop for more than 6 hours a day, I don't care the posture or the way I do it. But there are serious medical concerns regarding your posture, Ive read many boring articles on that. Recently I found out a Video made by Vodafone on via Anmol More. The video couldn get more intuitive, its speaks for itself. Take a look.
Video A: Using a laptop at home or office

Video B: Using your laptop while travelling or in a hotel

Any changes to your posture now?
