I’m three years older than John McCain and wish there were age limits for the highest office. We septuagenarians just aren’t as sharp as we were even if we think we are. Too bad, but that’s the way it is.
Perhaps there are exceptions but, although I still work full time, do the Times acrostics and most of their crosswords without a problem, read and listen to books as much as possible, whiz away on the computer and internet, take every vitamin known to the health industry, ride my elliptical daily, eat well, don’t smoke or drink, and weigh what I did in my twenties, I’m not the woman I was as little as five years ago.
I don't like to be less than--- nor do my contemporaries---but that's the deal nature made with us. We got our shot---sometime during those three score, ten years plus---and now, fair's fair, it's time for the fleet of foot, quick of mind and retentive of memory.
McCain may be one of the exceptions. I sure hope so. After all, heaven help us, he might win.

What people call "healthy" eating can mean anything anymore. what people call exercise can vary from running a triathalon to driving thru McD's drive-thru to get more fries.

Since when do we want young presidents?
Didn't Eisenhower, LBJ, FDR, Truman seem pretty old??
AGE equals experience. Why are we now devaluing that?

The Sunni/Shia thing was one thing, but the recent answer to a question about Spain/Zapateros was quite another. And, I've never heard him stutter and stammer quite so much as he has done lately.
If we can evaluate his experience, why shouldn't we be able to evaluate his judgment capabilities, which may be directly related to age?
