My 95-year-old mother and I watch this show every day. While not everything is of interest to us, we still have fun watching Jenna which is why we began watching the 4th hour of the Today show.
However, Jenna, regarding your etiquette segment on whether or not to wear sunglasses when speaking to someone: I say keep them on in the sunlight. I asked my eye doc what was the best thing I could do to protect my eyes - especially to keep away those cataracts as long as possible - and she told me wear sunglasses!
