I just got an email concerning a good online friend, Frank from Canada. He's had a mild heart attack and is in hospital. I'm surprised and worried by it. I like Frank a lot, he's a great bloke, and I'm concerned for him. It also brings home to me the concept of mortality. It is suddenly clear that one day I will have to face something which I've so far avoided: the death of someone I care for.

Frank, if you ever get around to reading this, my thoughts are with you, I hope you feel better really soon. I'll call in a few days, see if you're home and ok!
