That leads me to my next question. In some sense there must be some dichotomy in the fact that there's a lot of research out there but that it still has a long way to go. I notice in one place you say that “optimal exercises to preserve balance and reduce the risk of falls are not yet known”, and yet you have mentioned quite often that any increase in physical activities can reduce the chance of falls. I don't want to disparage the fact that even getting in shape makes you feel better—you can tell that from your husband—but there really is a lot more work to be done on what enhances someone's capability to be in better balance and reduce the risk of falls. Is that correct?
