Just wondering

Just wondering if any of you have tried to study statistics (not just basic stats but correlation, simple and multiple linear regression, etc.) when you aren't feeling well. That is me today. Took me about 3 hours to prepare my notes for the test, but I think it makes sense. We will find out. Now I am just wondering if my headache is from this flu bug, or statistics. That should take me the rest of the week to sort out! Hope your Saturday is headache free!
