An average man weighing 70 kg (154 lbs) is made-up of about 50 kg (110 lbs) or 50 litres (nearly 11 gallons) of water and requires approximately 3-4 litres (5-7 pts) of water a day to survive. This can vary considerable depending on the amount of physical activity undertaken and the surrounding temperature. For example, in the desert it is not uncommon to drink as much as 10 litres (2 gallons) a day. If the colour of your urine becomes too dark (light yellow is good), this is a good indication that you should drink more water.
