My grandma edeveloped P in her 93rd year and boy was she angry about it. Not upset just bl**dy angry that at that age her body could still do things to surprise her. But she got to see a whole new part of the hospital and meet the nice handsome young dermotologist man. (Her words not mine).
After a while i think the fact that her body could still do something unusual was a bit of a comfort in a strange way, you don't expect that many new things at the age of 93.
She died the following year, still with p and still fairly peed off about it.
