No fear
Almost twelve years ago now, I had an incident that led me to discover the hard way that I suffer from a condition called sick sinus syndrome. It has nothing to do with the nasal passages, but with the regulation of the heartbeat. As a result, I had a pacemaker fitted. (Strangely, so did Bob Skinner a couple of years later.) In an hour or so, I’m off to the clinic for my annual check-up, which will probably show that the battery life is running down and that I’m going to need a replacement within a couple of years. If that’s the case I’m not going to worry about it, just as I would advise anyone who is facing the need for a similar implant not to hesitate for one second but to go for it without fear. I played five-a-side football for over ten years with mine in place, and lots of other stuff beside, while barely remembering that it was there. Call this a public service announcement if you like, but I mean it. My pacemaker is my pal.

Hey Q: I got a port this year because of my crumby veins; best move ever. My Dad had a pacer/difib which served him well for many years. Beside, Bob needs you to keep ticking!!!
Passed with flying colours, Moe. Remaining battery life anywhere between eleven and forty-nine months, but I expect them to err on the side of caution in fitting a replacement.
