He was enjoying a glass of water.

Nobody's idea, I laughed. 'You just cannot live without water. All life started in the seas. The first animals were born in seas.'

'Seas? We don't survive in the seas.'

'Do you know that your blood is just as salty as the sea water? It is because all life started in sea water.

70% of your body is made of water.'

'If so, why do we have to drink?' he asked.

I laughed. 'Because you lose water. You cry, you sweat, you... You have to keep that 70% water in your body.'

Would you think that 70% of your  body is water? You have water everywhere. In your blood, in your tummy...

Without water ...

• your temperature would go up
• your eyes would be dry, and you would not see
• your blood would not flow
