Learn German and keep your brain healthy

According to the guardian “research suggests that bilingual people can hold Alzheimer’s disease at bay for longer, and that bilingual children are better at prioritising tasks and multitasking.”

Here are some benefits for our family:
– Bilingual kids learn multitasking a lot easier.
– Alzheimer symptoms will begin 5 years later.

One downside they don’t mention:
– Having to switch between languages causes headache, at least in the first few months of bilingualism!

One question remains unanswered:
The most-widely used, non-English language in American households is Spanish. How came that the Educational Attainment of Spanish native-speakers is lower than that of white monoglots?
