Whenever I get the mailings of all PD organizations I scratch my head and ask my dog : Why can't the FOUR BIG ONES , be ONE HUGE PD ORG. , running telethons, combining research, pushing Congress, ......why so many independent fiefdoms, ( one even had over a million stolen from it. ,,,,why so many personal 'turfs' All that scratching, to find out that the sebaceous glands in the skull sometimes go bananas with PD, and produce, and produce, and produce. Solution; shampoo daily or more . oh well, i'll bet there is more than one answer. ciao.
