Whitney Fan. I climbed the Mt Route at age 70 ( 3 weeks short of being 71) with no difficulty. In fact, I was following the legend Bob Rockwell who led our group of 4 and Bob is a couple of years older than I am. The ledges were of no particular difficulty either but this was in August and there was no snow or ice. We used no ice axes, technical gear or anything other than alot of water and snacks plus hiking poles.
I don't think you need to be at all gun-shy about climbing that route as long as you have done your training and altitude preparation and take it slowly and with caution.
