Hi my online penfriend am gonna answer honestly ! well let me tell u ! using the computer about 12h dosn't make u an ironwoman but maybe a half one huhu ! 4me i use my PC from 6 to 12 hours too but thts in vacation, in studing period i use it just 3h a day ! well ... am suffering from all consequences but i suffer from missing my Pc more ! here is some tips which i follow them for keeping my half helth : *Use desk lights instead of ceiling lights. Place the computer at a right angle to windows and install curtains or blinds if glare persists. *Teach urself to take frequent "eye breaks" -- totaling about 15 minutes off for every hour of computer use. In addition, have U take a 10-second break every 10 minutes. U can rest ur eyes by walking around or shifting ur gaze to look at far distances. *Staring can strain the eyes. Remind urself to blink frequently. When we stare at a computer screen for too long, our eyes lose lubrication and may become irritated. If u use a computer regularly, be sure u hav a vision checkup every year. P.S i believe i ll be blind after 5y or 6 ! thnx for the question & waiting 4 more ! ==> salam.

As a computer science student , computer means to me a tool to study, to learn , to play , to connect with others , surfing , .... usually in summer i'm stoned in front of my Pc from 7am to 1.00 am with a breaks , but i bet you all that no one spend more time than i do , why ? because sometimes i spend more than more than 25 hours per day !! because i stay10 hours on my Pc , and at the same times i'm downloading from my brothers pc , and fixing another Pc at once to if we add these 3 operation it takes more than 24 hours :-) hahha so as a result i found my self obliged to put a glasses 2 months after i had internet at house ! :-( i cannot resist to light as i did although i see 10/10 ! -nothing to add to what Wanna_learn said ! good job :-) P.S : the meaning of my real name in arabic is a kind of IRON or Steel , So i was born an IronMan, but Not a Nerd , hahahaha

honestly as you said; computer isn't just for the persons who need it on their works but even in schools. nowadays childrens are using it because the programs schools are demanding that. for me. it depends when i'm in school i use it for an hour by day. nd when i'm in vacancy, i use it for 2 or 3 hours/day. sometimes i didn't use it for 4 or 5 days.it depends; i use it for studying electronics, learning languages see my emails play games. and contacts with my freinds and my familly.

Even though I am a teacher , I am required to check my lap top computer for important emails several times a day & to take it to class to find information for students if I am unable to book the class into one of the computer rooms.
