I wouldnt eliminate Gerald Ford from any future list (even this year's), with someone of this stature (former US President) and this advanced age (93) you dont want to miss out on the inevitable. I mean he is going to be the longest lived president in history if he lives past November 11th. Also elderly people can go fast, Richard Nixon was very active up until the very end and then he had a stroke and was dead days later. Ford is not quite on the level of Ronald Reagan's living death for his last 9 years or so but he has reached the point where his public apperances are virtually nill and the only time he is in the news is for his birthdays, milestones, awards, and sickness.
One thing I found interesting though is that there were rumors that he was to ill to travel (hence why he didnt attend Clinton's presidential library dedication, etc.) supposedly because he is advised by doctors against flying in an airplane but he did manage to travel from Rancho Mirage, California to Vail, Colorado for his birthday this year, maybe the secret service drove him all the way to Colorado.
