hmm.. I usually jump online around 9.30am(if i so happen to get up early and I've not got errands to run or other life stuff) I'll sit online doing at least 5 different things at once breaking only for coffee or to grab something to eat and stretch legs and back...then i jump off the desktop to let my little sister on at around 4.30pm or 5..then i jump straight onto my laptop until midnight or sometimes if i get caught up in a conversation or posting on forums..it's so easy to not get to bed until 1 or 2 in morning. Although i only stay up that late if I have slept in or not tired. I don't do this every day. so on average 14-16(taking into account meal breaks and other interruptions.
