My neurologist told me a year ago, "No Problem on writing paperwork that you require a segway" and the next time I asked, he said no. He likes the segways for some folks because it keeps them from sitting so much, since you stand on the segway. Like for MS patients. Not sure exactly why he's changed his mind. O'well. I'm still pushing.
I'll probably mastercard one someday, for now I'm applying for a scooter. Don't want to, but that's about all everyone will support/pay for.
