How long can you read a manga without taking a break?

[Blackangel]

i can read it for 4 hours and may be even 5 hours too.
but not more than that

 

[Kaname]

I don't think I can read for that long man.
Probably 2-3 hours.

 

[Carol]

I can go on for a while but not for too many hours. I will be fine with 1-2 hours without taking any break

 

[Blackangel]

that's cool carol.
i don't think many people can do it.
