The thing in tonic water is quinine and although good for malaria and some heart rate abnornalities, I didnt know about the insect repellent bit. I bet she had fun adding gin to the tonic to make it drinkable
When I was in Thailand someone pointed out a fella who ate a lot of the scrunty-scrunty tree, or was it the bugaloo tree ? and he never got bitten. The Latin name was nux vomica, and I said look he should be dead, it contains strychnine [cos I kinda carry all these things around in my head] and the Thais said,
O no he not dead! he live!
and I said Ok next monument....It was Angkor Wat and I know this is in Cambodia, but you know you get the idea.....
