There are too many oldies who sink into unrelenting scepticism, scoffing at everything in sight and refusing to believe anyone could be honest or decent or well-meaning.
Yes, I'm aware of all the corrupt politicians, profiteering businesses, bullying bosses and foot-dragging bureaucrats, but I don't allow them to poison my general view of life or my attitudes to other people.
I've had a few periods of acute cynicism over the years, which didn't do me any good but only spoiled my enjoyment of life and turned me into a miserable sod.
Cynicism is apparently bad for your health too. A research study in 2014 found that people with high levels of cynical distrust were three times more likely to develop dementia than people with low levels of cynicism.
It strikes me that cynicism is closely related to misanthropy - disliking human beings and avoiding human society. But I'm not misanthropic. I don't (in general) hate human beings, I just find the behaviour of some of them baffling and peculiar. I certainly wouldn't actively shun human company, that seems a rather eccentric thing to do.
One thing that feeds cynicism is that unpleasant experiences stick in the memory more vividly than pleasant ones. I'll remember someone who shouted abuse at the bus driver but I won't remember the person who gave up their seat to an unsteady oldie. From there it's easy to generalise quite wrongly about how nasty people are.
Cynicism, be gone. I have no use for you.
