It seems this is the season for medical issues.
My FIL has Parkinson's Disease and it is worsening. He fell on Monday. He's fallen several times in the past months. But knocked his head a good one this time - busted furniture and a lamp in the fall. Great timing as we head into what, for many, is the busiest time of year. But, we have no control over illness...just like those spontaneous boners.
The cock will do what the cock does without provocation.
