Are you male or female?
As a rule of thumb men should drink more than women. Generally, men are bigger than women and have a more active metabolism.

Are you large or small?
The larger you are, the more you should drink.

Do you have a job where you sit down all day, or is your work physically demanding?
Of course you’ll need to drink more water if you cut down trees all day long.

Are you young or old?
The older you get, the less thirsty you feel even when your body is screaming for liquid.

Check the colour of your urine!
It’s easy to find out if your water reserves are low. Check the colour of your urine as it’s a good indication of whether you’re low on water on not. If your urine is a deep yellow colour you are low on liquid. The clearer you urine is, the better your liquid balance is. If in doubt ask your physician for advice.
