I think it's one of the big winners out there in terms of something that might be useful for people if they're willing to practice it.

Some people are perpetually tardy because they don't have a good sense of time, or try to squeeze too much into the time they have available. Others are late because it's a passive-aggressive way to be in control.

Most people have experienced back pain at some point in their lives. Sometimes the pain goes away in a few days, but sometimes it lasts for weeks. And unfortunately, the treatments offered by modern Western medicine are only modestly effective.

The study suggests that for people who are looking to do something for themselves, you could clearly say that yoga is the best.

Although exercise is one of the few proven treatments for chronic low back pain, its effects are often small and we haven't known whether one form is better than another. So we designed a study to evaluate the effectiveness and safety of a gentle program of yoga for people with this condition.

We see people who are going around looking for differences in the props (odds) between the different properties.
