My wife was very happy for me to leave. She helped draft the letter.
No, it's not the 42 years; it's about having a sense sometimes—how much more value-added could I be? And that's why I was a bit reticent to come here. I didn't see myself as being value-added today. I had given my testimonies to you previously. My sense is that when the time comes, you know it's there.
I've always said that it's important that when you get up in the morning you want to go, and if that feeling is not there, that's the signal.
