Reasons to quit: Crouching takes stamina.

lul.

Have fun crouching through your daily live and tell me how easy it was. Last but not least you are not crouching but rather sneaking and that gives you advantages. Sneaking all day would be some sort of easy mode.

Meanwhile: Why you are sneaking that much? I couldnt think of any moment where would sneak as much. Its kinda funny and sad at the same time what people come with to complain.
