Self-experimentation, though hardly a new idea in the sciences, remains rare. Many modern scientists dismiss it as being not nearly scientific enough: there is no obvious control group, and you can hardly run a double-blind experiment when the researcher and subject are the same person. But might the not-quite-scientific nature of self-experimentation also be a good thing? A great many laboratory-based scientific experiments, especially those in the medical field, are later revealed to have been marred by poor methodology or blatant self-interest. In the case of Roberts, his self-interest is extreme, but at least it is obvious. His methodology is so simple - trying a million solutions until he finds one that works - that it creates the utmost transparency.So in other words, it's completely unscientific, but that's OK.
So here's something that's worked for me. For the past several months I've been plagued by an increasingly painful lower back region. When it got so that it was very painful to bend over, I found various exercises on the net, and the "pelvic tilt" did wonders for me. (from Low Back Pain).
Then I tried the Advanced Back Stretch:
(from Flexibility Training). That worked even better. For me. This time.
