A few months ago I had possibly the best massage I’ve ever had. My masseuse, Anouschka, had learned her skills in a remote village in Thailand where she’d lived for a year in a mosquito-infested hut with the local medicine woman. I asked how she’d survived the mozzies. Anouschka explained that she’d just done what the villagers do: eaten a diet heavy in chilli and garlic which seeps through your pores in the night and stops you getting bitten.
