Hello, you're about to listen to a BBC podcast, and I'm Ed Gamble, host of another BBC podcast,

The Traitors Uncloaked. But my show is available only on BBC Sounds, just like Ellis and John's

reason or another. I'm 84 years old. I'm physically very fit and walk and swim.

And recently I've been under quite a lot of stress.

And I've been finding that I'm losing my memory, short-term memory, forgetting things.

And I obviously saw my doctor who arranged me to have a scan.
