"If you are elderly or infirm, you may be able
to auxiliary pioneer by spending a little time each day in the ministry." The word infirm means "weak, feeble, not
stable, or frail."
The hell you say! 
You know, this is one of of the reasons why I left. There were times when, due to my illness, I was barely able to hobble into the KH, and sometimes I had to sit in a chair in the vestibule because I couldn't make it to the main part of the Hall. You would think that the elders would be glad that I at least showed up, but no, after a few times times they removed all the chairs in the vestibule in order to force me to go in. That was when I started sitting in the ladies'. Then I stopped showing up altogether. There was no way I was going to kill myself for them!
