Once you reach a certain age, things begin to go off inside you, and so a regular program of maintenance is called for. Part of this is them going in to clean out any odd growths from your digestive tract. And so it's off to the doctor for a rather uncomfortable morning.
Actually, the morning should be fine; the prep work last evening was the uncomfortable bit.
The last one was 6 months ago, and they found (and removed) something sort of big and sort of strange. Today is to check that they got it. Hopefully it will be in and out, and good news from the doc. I expect that if it's not good news it would be pretty bad news, so we've all learned the importance of a proper maintenance schedule, haven't we.
Blogging has been off for a bit and will continue to be off for a bit.
UPDATE 11 August 2017 12:50: Back home with a clean bill of health. A little woozy still, but don't need another "oil change" for three years. Go team me!
