I had to think about all of the very valid points that have been made thus far and have a reverse situation: why is too young, too young? Certainly there are many young people out there who have the mental and physical wherewithal to drive a school bus but because of their age, they cannot. There is a start up driving age for private vehicles and I imagine that there are some local rules and regulations that also apply to when a person is old enough to drive a school bus. In this case, we have an aged lady who I imagine has driven a school bus for the last 50 years or so and probably the same route day in and day out during the school year. (Mere supposition of course) She probably knows every doctor, lawyer, and trash collector that previously rode her bus when they were children which might make it all the more painful to say nice job and it's time to sit down and let the 30 year olds get a chance. I am seriously trying not to be cold hearted but if there are rules about the age when someone is deemed by the laws of insurance averages concerning a starting age then there should, in kind, be an ending date also. If someone reaches the end age then offer them a desk job or give them their gold watch, a farewell party and a nice pension wherever possible. I know, I too really want to be superman all the days I have on this earth but there will come a time when I will have to realize that my cape is rumpled and I'll have to stick to leaping over ant hills in my yard because even the shortest building will be too tall challenge.
