I'm back in DC practicing this week and learned that one of my yoga teachers had B-cell lymphoma and has been going through chemo. He looks great I would have had no idea if he hadn't told me. He has continued his practice through all of his treatments despite his body feeling like "sludge." He just started moving more slowly and holding postures longer. He said he had "chemo brain" and some neurologic problems from the medication, but attributes how well he is doing now to his yoga practice... I bet he's right.
On top of all this, he doesn't have health insurance and laughed at the thought of ever being able to afford it.
