How old is too old?

I was talking to my parents the other day on the phone about William Daniels (Mr. Feeny from Boy Meets World) who is 95 years old. My dad said "See that's just too old." And I gasped! Not because it was loosely suggesting a world without Mr. Feeny, but because while I do think 95 is OLD, I don't think I'd ever say it was TOO old?

So I ask... what is TOO old to you? I'd say 102. At that point, you've gotten your Smucker's 100th Birthday shoutout on the Today Show from Al Roker, and then some — what more could you need?
