Water is the source of life. We cannot live without it. Water helps us to live longer. People who drink lots of water are healthier. They get fewer health problems and old-age illnesses, like heart and lung disease. They live longer than people who do not drink a lot. Drinking water makes us look younger.

Researchers looked at 11,000 people over 30 years. The people went to hospital five times or more – three times in their 50s, and twice in their 70s, 80s and 90s. Water may slow down ageing and help us to live a longer, disease-free life. Half of us do not drink enough. An adult needs over 1.5 litres of water every day.
