English is my first language. My Spanish used o be better when I spoke it more often. Most of my Russian comes from when I played an English Bobbie pursuing a Russian Spy in a production of "See How They Run." I worked with a beautiful young Russian emigrant a number of years ago. She tried to teach me some words and phrases. But, they did not stick. I worked with a doctor who was fluent in 12 languages. My brother, who spied on the Chinese, spoke 6. The doctor told me that there is a part of the brain that is used more by bilingual people. He suggested that it may be larger for some reason in some, and it grows with each new language. I jokingly said he should work on a language "Viagra." He did not laugh.
