I guess the age one reverts brings it's own unique set of difficulties. Having been what would be described as elderly at the time of my reverting. I faced different difficulties. My biggest difficulties were/are:

Changing over 60 years of deeply ingrained habits. (ie Chain Smoking, beer drinking party animal)

Learning to properly respect women and value them as true Sisters.

Avoiding some old acquaintances

Really understanding that true freedom comes from full submission

It is difficult for an old man to accept the fact that he doesn't know everything.
