One of the buddies I worked with during my photography stint had MS. He was often near collapse, trying to buffalo through the day. It seemed random until it became almost constant.
He woke up in the hospital sometimes; recently quite often, until this morning when he didn't.
We stayed in touch, but not like barbecue on the weekends or anything. We used to bike together for a couple of years, but for about a year he has been too weak.
MS does some ugly things to people.
On a brighter note, one of my night watch/neighbor buddies has been talking about retiring from his day job for over a year and today he did so. What I did not know was that he was a kind of local celebrity to the next county over where he worked. He is a couple of years older than I am, but he had been with the hospital system for FORTY (fucking) years.
In fact, I found out after seeing him on the early local news that he was The First fully trained EMT in the county.
