Heh, this is interesting. I'm 53 dxd 4 yrs. From Ontario where 95 is hot with the humidity that always travels with it. Now if anything goes wrong with me I debate in my mind if it is another Parky symptom rearing its ugly head, or I'm growing older or whatever. After 4 days of this heat, I seem to be not functioning as well as I used to. I work construction so it always was drink lots of water, sweat and carry on. But with this heat wave, I feel weak, sweating like crazy, and just not functioning like I should. Today I wondered if it possibly could be PD related. Comments on this thread lend some credence to that thought, thanks. If my brain was a shiny new vinyl record, Pd symptoms are the scratches that keep appearing on it. john
