Let me set the scene. its 3 am and our little one awoke for a feed and had a good burp before he started expressing all the signs of being tired again and ready to go back into his cot….great! we thought as we were also quite tired…..but he didn’t settle.

Seeing is believing. Or is it?

Observation has been the principle of empirical scientific method since Aristotle, who viewed scientific inquiry as ‘…progression from observations to general principles and back to observations’.

There were about 20,000 POWs in the camp, of whom a quarter were British. The diet was about 600 calories a day and we all had diarrhoea. In addition we had severe epidemics of typhoid, diphtheria, infections, jaundice, and sand-fly fever…
