Just wanted you to know that I remember what your original post read. What do you guy's think? Well asked question. It wasn't that long ago an elder modeler lost site of his own plane and killed himself with it.(Arizona I think) Who know's the whole story behind this tragic accident, seem'd the only thing not in his favor was his age. I have no answer, but , is it a concern? it is to me. Ask yourselves this. If an elder urologist hands shake uncontrollably, should he be allow'd to perform vasectomies, I guess on some of you, the answer would be yes, NOT!!!
