More than 10 hours in average for the weekday including working hours. Weekend will be less, maybe 2~3 hours
i stay online about 6-8 hours daily. nothing special to work looking for some quality work to do over internet.
I am a business man so i have to work on PC most of time and it is helpful for me in my work. I have to mail it, chat with my Clint, send some important file and folders so it is most important thing in my day to day work. I used my computer for work more than 14 to 16 hours a day.
Heym maybe u could change your life style a little, I think that long huors are bad for your health!!
12 hours daily as of now due to some other offline work but used to work 14-15 hours daily previously. DON.
