One of the better things I did was to become the resident troll of a BBS called Lothlorien. Basically, it was a gathering place for geeks and outcasts who owned a decent modem.
Last Friday, we had a small gathering and they straight-up told me that I lost a lot of weight and this could mean that I might have cancer. Fortunately one of the gang is now a doctor and we reduced this to the possibility that my hyperactive thyroid has relapsed. This was really helpful as I have a medical appointment that afternoon to get my problem resolved once and for all. I've had dry lips and lost 4kg of weight and get tired very easily when exercising.
Unfortunately for me, I was the last patient at the government hospital on a Friday evening and there was no way anyone could administer a blood test and wait for the results to be out....
