Of course, there are things you can do, ice cubes you can acquire, to cool down the water in the kettle (e.g. medication, cognitive behavioural therapy (CBT), exercise etc). Emotionally, there are insulated gloves you can wear to help you handle the current temperature of your Parkinson’s. Alternatively, you can make the temperature of the kettle feel higher by dragging yourself into an unknown future built on negative expectations.
I can’t do anything about the fact the Parkinson’s kettle has been switched on but I can do something about how to react to the current temperature of the kettle.
