Microbiologists have been growing microbes on agar plates for nearly 150 years, but agar’s discovery dates back to a happy accident in a mid-17th-century kitchen. Legend has it that on a cold winter day, a Japanese innkeeper cooked tokoroten soup, a Chinese agar seaweed recipe known in Japan for centuries. After the meal, the innkeeper discarded the leftovers outside and noticed the next morning that the sun had turned the defrosting jelly into a porous mass. Intrigued, the innkeeper was said to have boiled the substance again, reconstituting the jelly. Since this discovery, agar has become a staple in many Japanese desserts, from yokan to anmitsu.
That is not only a sadness and a loss, but becoming an aged society is a cultural and economic threat. Older people, by and large, are not the innovators or new thinkers. An ageing society risks declining in optimism, creativity and, above all, risk-taking: a top-heavy preponderance of older people makes for a conservative and fearful electorate. We are there already – and it’s getting worse.
