When I had my baby, more than 30 years ago, I didn’t pay much heed to all the food restrictions and health tips that everybody else in Asia seems to be following. I considered myself a modern, emancipated woman who knew better than my elders what my body needed, and that included daily showers and hair washing although those were taboo. Now, perhaps, with hindsight, I should have paid more attention to all that advice, because my bones ache on rainy days, something the old wives warned about.
