How much time do you spend on a PC a day?

Most of my day to be unfortunately honest.
I get up at 6, start my bus commute to work at 7 (which takes just over one hour) where I spend the whole journey playing games on my laptop.
Then I work from 8.30 - 4.30 on my computer at work, commute 1 hour back with the same gaming or at least reading on my phone if there are no seats.
I often game in the evening when I get home, and at least a few hours a day on weekends.
