The blog post gives the example of how more distractable old people can outperform less distractable young people on a specially contrived mental test. Similarly, if you put a bunch of junk for someone to trip over on the way to the bathroom, it would be the old person who tripped over it all that would remember it on his return.

But in what real-world mental challenges do old people have the advantage over the young? In mathematics, for example, you're an old man at 30. Except for Erdős the meth-addict, of course.
