Judging from my own accquaintances, a lot of Germans take up cycling after their first heart attack. This may bias the sample.
The "traffic jamming" style of riding common in the USA and UK is not really so prevelant in continental Europe.
You have to look really carefully at the sample for any report, but esp for cyclists. One report compared city commuter cyclists to extreme elite MTB riders for impact damage to the genitals. Of course the off-roaders suffered far more impact damage. The newspapers got hold of this and gave the impression that all cycling resulted in MTB style bruising and damage.
