My progression started in the legs & they are now useless. Since I still retain good strength in the upper body region I am using hand controls for the time being. When my upper body begins to fade I will turn in the keys. Unfortunately we are out in the country and everything requires a ride in the car, with 2 active young children involved in many activities I spend a fair amount of time taking them to practice, meetings, etc. Our oldest will be 14 in a couple of months, I hope that he gets to return the favor & drive me about for a little while at least.
