Perhaps OP meant that he had been dealing with a knee injury, and that doesn't have much to do with "mental frailty" at all: https://www.espn.com/tennis/story/_/id/30821027/roger-federe...

EDIT: Actually the article is from 2012, so I assume its because many of Federer's best years were still ahead of him.

The original article (from The Economist) is from 2012, so whatever the author was referring to was not the same as the injuries discussed in your 2021 article (from ESPN).

Hence the edit.

Which was made after my comment.

I think there was some page-refreshing asynchrony here, either on your end or mine. But I appreciate that you attempted to correct me, so thank you.
