MIddle Ages

I've reached middle age.

Two days ago, I was trying to read a book in bed and I was having trouble focussing.  Initially I thought maybe my eyes were tired,  I'd been working on the 'puter a lot.   As I struggled to focus,  it dawned on me.

I moved my hands back a bit, so that the book was a tiny bit further away.  The words swam into focus.

It's happened a couple of times since.

Bother.
