Many elderly people, especially if they are in their nineties or hundreds, refuse to drive even if they are in perfect health. The reason for that is because anything could happen, and they want to be on the safe side. The perfectly healthy elderly men and women may have transportation as well. They may have vehicles at their apartment or nursing home that will take them where they need to go. They may want to go to the movies or to a home of a relative. Make sure you check the times for pick up or ask what they are so you will be on time.
Most of the time the reason they are living in nursing homes or apartments is because they do not want to be alone, and they know their will be people there to help them if needed. The benefit to using medical transportation in this non-emergency situation is that you have the freedom to go when you want and where you want.
