From Gerardo Corripio, Tampico, Mexico:

Reading the article, "Work that Body," in the December 2006 issue of the Ziegler, I agree especially with the topic of mind-body connection. Thus, it's recommended for people who don't know yoga--like myself--to meditate at least 15 minutes daily.

According to recent studies, meditating regulates arterial pressure and oxygenates the brain, among other great benefits. I've seen these benefits in myself since I began practicing meditation some time ago.

Regarding exercise, however, my experience with the electric treadmill has been negative. I started out too fast, injuring my waist so badly I had to go to the doctor. Since then I've been afraid to use a treadmill again. I'd appreciate any suggestions on how to use this device, which I've heard works wonders.

Reading the May article, "Singing in the Brain," it's wonderful how birds learn to sing. I'm living through the experience of hearing a young canary in this process. A few months back, the bird would sing in single notes; later it combined these. Once it got the hang of things, it would practice softly to itself. Nowadays, it sings exactly like its father.

Thanks for letting us readers learn new things in these great articles. Lastly, congratulations for being with us blind people worldwide for 100 years! May the Ziegler live another 100, because it's a great way for us in non-English-speaking countries to practice the language as well as to be informed by such great articles.
