We sat behind Fathers Pfeiffer and Hewko at Fr. Gruner's funeral Mass. I observed that he seemed a little off, and presumed it was extreme fatigue for obvious reasons.
In retrospect to this news, and knowing how bronchitis /pneumonia operates due to the sufferings of a close family member, I think it's onset was beginning.
There's a good product that this family member uses that helps him tremendously. If anyone connected to Father would like the information, please PM me.
