It's dangerous out there for us guys that's for sure. But my love for cycling and the immense health benefits it provides vastly outweigh any ideas I might have of calling it a day.
My missus hates me going out on the bike and I learned years and years ago that talking about my ride and the near misses I've had during it were not helping her one bit. We have a kind of cycling "omerta" in our house......never talk about my rides!!
There are things we can do such as use quieter roads at off peak times if possible. And also stop chasing PB's all the time so you become happier, and safer, cycling at a slightly slower pace.
But even then it only takes one lapse of concentration on your part and/or a lapse of concentration by another road user in a much larger vehicle than yours, and that can be it.
