Jenni’s 72-year-old grandfather has difficulty understanding her when she speaks, but he seems to understand her father much better. why might this be?

The reason her grandfather might understand her father better than hers could be because it's his son. Her grandfather raised her father. Which could effect their communication.

if this is true of false i think it would be true

so i really think that most of the health care industry be doing more bad than good.
