Oh, to be bilingual in the Anglosphere

"There are many reasons to be grateful for being part of the "Anglosphere". English is the world's lingua franca, the language of science, technology, business, diplomacy and popular culture. That probably explains why it is the world's most widely spoken language. It probably also explains why native English speakers are so reluctant to learn a second language. It's not worth the effort.In 2005, the European Commission carried out a survey of the European Union's 25 member states. The two with the lowest rates of bilingualism - defined as being able to hold a conversation in more than one language - were the UK and Ireland. About two-thirds of people in these countries speak only English. It's a similar story wherever English is spoken as the mother tongue. Only about 25 per cent of US citizens can converse in another language. In Australia the rates are even lower. Compare that with continental Europe, where multilingualism is the rule rather than the exception. More than half of EU citizens are bilingual, and not just because they live in countries like Luxembourg with multiple official languages. Even in France, which has only one official language and is immensely proud of its linguistic heritage, most people speak a second language. Again, that is largely down to the dominance of English. Across Europe, English is by far the most commonly learned language. High levels of bilingualism are not driven by a general desire to learn languages but a specific need to learn English. People born in countries where English is not the mother tongue have their own reasons to be thankful: being bilingual is good for your brain . It doesn't matter whether you are brought up in a bilingual household or learn a second language later in life, speaking more than one language improves cognitive function across the board, from planning and working memory to concentration and multitasking. Most significantly, being bilingual can sharpen the ageing mind, delaying the onset of dementia in those vulnerable to it by as much as half a decade. It is one of the most effective forms of "brain training" available."
