Right, because I just get the sense, and I hope this doesn't cause offence to anybody, that with respect to technology for prevention, we're still at the days where computers came into our homes and when we asked what we would do with them, we were told, “Well, put your recipes on them.” It really didn't make a lot sense to be typing your recipes out onto a computer. I just get the feeling that this is where we are on the prevention, which isn't to suggest that maybe there's not a great future for it, but it seems we just haven't found it yet.
You mentioned walking, and that seems like a sensible thing to do that doesn't require a phone.
