Interesting book recommendations, thanks! They remind me of some literature I've heard of that claims it's possible to cure most eyesite problems without glasses.

On the back pain subject, a friend's wife decided to go against her doctor's advice to have surgery for her back pain (after which, best case scenario, she would likely need a cane for mobility). She chose some non-invasive procedure, and she's now running around chasing her children.

Some days, I just have no faith in doctors.
