Love the math example. You must of known I teach math to middle school special ed kids. UGH. When I have more blood work done, I will ask them to check the TSH levels if they will. They may not since it was not ordered. I go back to one of my many Drs in May and will ask about it then as well, if I remember. darn chemo brain. I even wrote down a list of questions to ask and forgot that at home too. UGH. Both sides of my equations are not balanced yet. Sometimes I wonder if they ever will again.
