Was thinking of my trusty bike - utterly useless this morning because of a flat tyre - and drew the parallel with patients suffering from angina.
We need oxygenated blood to get to our hearts, while the bike, older than me now in bike years, she's 16, needs air in that front tyre.
My bike is my weapon against heart disease, helping me to return to fitness and perhaps some reversal of the condition. That wheel will be off for surgery any minute now.
I'm resisting the urge to use my repository of dad puns. For now.
More from the Angina Liberation Front soon....
