Thank you Susie. I know I've got this coming in the next few years. My dad is nearly 79, and on many different tablets for various things. He had two heart attacks about 7 years ago.

Of course, my dad is different to yours. He's changed as he's got older, but not because of Parkinson's. When he was younger, he just had a bad temper and would get angry easily. As he got older, he gradually mellowed out. My mum often complains about how useless he is, but I sometimes tell her, "You should just be glad he's not as angry as he used to be."
