What an Ass!
According to Fox's website, he was diagnosed with Parkinson's Disease in 1991, which means he's been living with the disease for around 15 years. Anyone who either lives with or knows someone who is living with Parkinson's Disease knows that, like other diseases such as cancer, Parkinson's has several "stages".
Stage 1: Mild tremors, loss of balance/posture, facial grimaces
Stage 2: Symptoms are bilateral, difficulties walking, maintaining balance, everyday tasks are
Stage 3: Symptoms of stages 1 and 2 are more severe, with difficulties walking or even
standing, and noticably slower physical movements
Stage 4: Rigid movements, bradykinesia (extreme slowness of movement) , inability to live on
their own, sometimes tremors lessen during this stage
Stage 5: The disease takes over all physical movement, may not be able to walk or stand alone,
may be unable to take care of self

Depending on the stage, the day of the week, the amount of sleep a person has gotten, what time of day it is, if they are "in between" meds, if their current meds aren't working, their stress level, and how the stars are aligned in the night sky, a person's symptoms can worsen or get better from one day to the next. To have your mind intact and be able to watch your body deteriorate is a horrible thing to deal with, especially because your dependence on a caregiver is inevitable, which means a loss of independence. Can anyone honestly blame Michael J. Fox for endorsing a senator who is interested in finding a cure for this disease? Wouldn't you?
