No, not sci-fi, but more to do with how we tie ourselves in knots and keeping to ourselves problems.
This thread had its genesis in a comment by Retro Grouch about how helpful it is knowing that others had experienced something of the frustrations he is having getting motivated again with his cycling.
It got me thinking. It's a feeling that 50+ people can leave themselves open to for reasons such as becoming more isolated as family grows and leaves home, or the job bosses get younger and younger.
There have been occasions when I have kept things to myself only to find others had experienced them, too.
I can think of a female boss I used to have who was the domestic partner of the chairman. She was extremely difficult to work for and with, and when I left the organisation after three years, I felt it was all "my fault".
Then I found out she treated others the same way, and they had similar feelings. Another, luckily for him, was able to cope with the battering and survived much, much longer in the business... without it affecting his nice guy-ness.
I've also had the odd medical issue. In one case, I had an enlarged gonad, and when my doctor diagnosed it as being non-malignant and nothing really worth worrying about, he related the tale about an Italian familly for whom the family symbol was three balls.
So, what have you done that has left you feeling as though you are the "single voice", then you've found you are but a member of a much larger choir (so to speak)?
