Steffi I know what you mean....walking is not just walking anymore, it's a study. If I don't pay attention, I walk like I've been drinking, or like a puppet on strings. Most things these days take a concentrated effort.
Your comment about practicing your vocals, is so true, too. My voice goes pretty soft, so to strengthen it I sing in the car, at home, in my office (when no body is around)....I probably would set all the dogs howling if I sang outside, but it sure feels good to belt it out!
I am just getting back into high heels, but prefer leather boots! oolala!
