If you asked her (Margaret Thatcher) about Sinai, she would probably think it was the plural for sinus.
I really worked very hard to bring my voice back because I used to have a good voice, and to try to do my exercises that I remember from Yale and all the things in the olden days, clearing your sinuses and all that.
Life is better when your sinuses are clean, when your arteries are clean, and when your digestive tract is clean.
